What are the treatments for Breast Cancer ? | Once breast cancer has been found, it is staged. Staging means determining how far the cancer has progressed. Through staging, the doctor can tell if the cancer has spread and, if so, to what parts of the body. More tests may be performed to help determine the stage. Knowing the stage of the disease helps the doctor plan treatment. Staging will let the doctor know - the size of the tumor and exactly where it is in the breast. - if the cancer has spread within the breast. - if cancer is present in the lymph nodes under the arm. - If cancer is present in other parts of the body. the size of the tumor and exactly where it is in the breast. if the cancer has spread within the breast. if cancer is present in the lymph nodes under the arm.

What is (are) Breast Cancer ? | There are two types of breast-conserving surgery -- lumpectomy and partial mastectomy. - Lumpectomy is the removal of the tumor and a small amount of normal tissue around it. A woman who has a lumpectomy almost always has radiation therapy as well. Most surgeons also take out some of the lymph nodes under the arm. Lumpectomy is the removal of the tumor and a small amount of normal tissue around it. A woman who has a lumpectomy almost always has radiation therapy as well. Most surgeons also take out some of the lymph nodes under the arm. - Partial or segmental mastectomy is removal of the cancer, some of the breast tissue around the tumor, and the lining over the chest muscles below the tumor. Often, surgeons remove some of the lymph nodes under the arm. In most cases, radiation therapy follows.

What are the treatments for Breast Cancer ? | Even if the surgeon removes all of the cancer that can be seen at the time of surgery, a woman may still receive follow-up treatment. This may include radiation therapy, chemotherapy, or hormone therapy to try to kill any cancer cells that may be left. Treatment that a patient receives after surgery to increase the chances of a cure is called adjuvant therapy. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the treatments for Breast Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Even if the surgeon removes all of the cancer that can be seen at the time of surgery, a woman may still receive follow-up treatment.

What are the treatments for Breast Cancer ? | Radiation therapy uses high-energy x-rays or other types of radiation to kill cancer cells and shrink tumors. This therapy often follows a lumpectomy, and is sometimes used after mastectomy. During radiation therapy, a machine outside the body sends high-energy beams to kill the cancer cells that may still be present in the affected breast or in nearby lymph nodes. Doctors sometimes use radiation therapy along with chemotherapy, or before or instead of surgery. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the treatments for Breast Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Radiation therapy uses high-energy x-rays or other types of radiation to kill cancer cells and shrink tumors.

What are the treatments for Breast Cancer ? | Chemotherapy is the use of drugs to kill cancer cells. A patient may take chemotherapy by mouth in pill form, or it may be put into the body by inserting a needle into a vein or muscle. Chemotherapy is called whole body or systemic treatment if the drug(s) enter the bloodstream, travel through the body, and kill cancer cells throughout the body. Treatment with standard chemotherapy can be as short as two months or as long as two years. Targeted therapies, usually in pill form, have become more common and focus on either a gene or protein abnormality and usually have few adverse side-effects as they directly affect the abnormality and not other cells or tissues in the body. Sometimes chemotherapy is the only treatment the doctor will recommend. More often, however, chemotherapy is used in addition to surgery, radiation therapy, and/or biological therapy. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the treatments for Breast Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Chemotherapy is the use of drugs to kill cancer cells.

What are the treatments for Breast Cancer ? | Hormonal therapy keeps cancer cells from getting the hormones they need to grow. This treatment may include the use of drugs that change the way hormones work. Sometimes it includes surgery to remove the ovaries, which make female hormones. Like chemotherapy, hormonal therapy can affect cancer cells throughout the body. Often, women with early-stage breast cancer and those with metastatic breast cancer -- meaning cancer that has spread to other parts of the body -- receive hormone therapy in the form of tamoxifen. Hormone therapy with tamoxifen or estrogens can act on cells all over the body. However, it may increase the chance of developing endometrial cancer. If you take tamoxifen, you should have a pelvic examination every year to look for any signs of cancer. A woman should report any vaginal bleeding, other than menstrual bleeding, to her doctor as soon as possible. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the treatments for Breast Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Hormonal therapy keeps cancer cells from getting the hormones they need to grow.

What are the treatments for Breast Cancer ? | Certain drugs that have been used successfully in other cancers are now being used to treat some breast cancers. A mix of drugs may increase the length of time you will live, or the length of time you will live without cancer. In addition, certain drugs like Herceptin and Tykerb taken in combination with chemotherapy, can help women with specific genetic breast cancer mutations better than chemotherapy alone. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the treatments for Breast Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Certain drugs that have been used successfully in other cancers are now being used to treat some breast cancers.

What is (are) Colorectal Cancer ? | How Tumors Form The body is made up of many types of cells. Normally, cells grow, divide, and produce more cells as needed to keep the body healthy and functioning properly. Sometimes, however, the process goes wrong -- cells become abnormal and form more cells in an uncontrolled way. These extra cells form a mass of tissue, called a growth or tumor. Tumors can be benign, which means not cancerous, or malignant, which means cancerous. How Colorectal Cancer Develops Cancer of the colon or rectum is called colorectal cancer. The colon and the rectum are part of the large intestine, which is part of the digestive system. Colorectal cancer occurs when tumors form in the lining of the large intestine, also called the large bowel. Colorectal cancer accounts for almost ten percent of all cancer deaths in the United States. The risk of developing colorectal cancer rises after age 50. It is common in both men and women. Colorectal Cancer Can Spread Sometimes, cancer cells break away from the malignant tumor and enter the bloodstream or the lymphatic system where they travel to other organs in the body. Among other things, the lymphatic system transports white blood cells that fight infection. When cancer travels or spreads from its original location in the colon to another part of the body such as the liver, it is called metastatic colorectal cancer and not liver cancer. When colorectal cancer does spread, it tends to spread to the liver or lungs. Cure Rate for Early Detection Today there are more ways than ever to treat colorectal cancer. As with almost all cancers, the earlier it is found, the more likely that the treatment will be successful. If colon cancer is detected in its early stages, it is up to 90 percent curable. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What is (are) Colorectal Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> How Tumors Form The body is made up of many types of cells.

Who is at risk for Colorectal Cancer? ? | Scientists don't know exactly what causes colorectal cancer, but they have been able to identify some risk factors for the disease. A risk factor is anything that increases your chances of getting a disease. Studies show that the following risk factors may increase a person's chances of developing colorectal cancer: age, polyps, personal history, family history, and ulcerative colitis. Age Colorectal cancer is more likely to occur as people get older. It is more common in people over the age of 50, but younger people can get it, too. In rare cases, it can occur in adolescence. Polyps Polyps are benign, or non-cancerous, growths on the inner wall of the colon and rectum. They are fairly common in people over age 50. Some types of polyps increase a person's risk of developing colorectal cancer. Not all polyps become cancerous, but nearly all colon cancers start as polyps. Diet The link between diet and colorectal cancer is not firmly established. There is evidence that smoking cigarettes and drinking 3 or more alcoholic beverages daily may be associated with an increased risk of colorectal cancer. Personal History Research shows that women with a history of cancer of the ovary, uterus, or breast have a somewhat increased chance of developing colorectal cancer. Also, a person who has already had colorectal cancer may develop this disease a second time. Family History The parents, siblings, and children of a person who has had colorectal cancer are somewhat more likely to develop this type of cancer themselves. This is especially true if the relative had the cancer at a young age. If many family members have had colorectal cancer, the chances increase even more. Ulcerative colitis Ulcerative colitis is a condition in which there is a chronic break in the lining of the colon. Having this condition increases a person's chance of developing colorectal cancer. Genetic Mutations Researchers have identified genetic mutations, or abnormalities, that may be linked to the development of colon cancer. They are working to unravel the exact ways these genetic changes occur. Recent results from The Cancer Genome Atlas study of colorectal cancer point to several genes (BRAF and EGRF among others) that may increase risk. If You Have Risk Factors If you have one or more of these risk factors, it doesn't mean you will get colorectal cancer. It just increases the chances. You may wish to talk to your doctor about these risk factors. He or she may be able to suggest ways you can reduce your chances of developing colorectal cancer and plan an appropriate schedule for checkups. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: Who is at risk for Colorectal Cancer? ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Scientists don't know exactly what causes colorectal cancer, but they have been able to identify some risk factors for the disease.

What are the symptoms of Colorectal Cancer ? | Most cancers in their early, most treatable stages don't cause any symptoms. That is why it is important to have regular tests to check for cancer even when you might not notice anything wrong. Common Signs and Symptoms When colorectal cancer first develops, there may be no symptoms at all. But as the cancer grows, it can cause changes that people should watch for. Common signs and symptoms of colorectal cancer include: - a change in the frequency of bowel movements - diarrhea, constipation, or feeling that the bowel does not empty completely - either bright red or very dark blood in the stool - stools that are narrower than usual - general abdominal discomfort such as frequent gas pains, bloating, fullness, and/or cramps - weight loss with no known reason - constant tiredness - vomiting a change in the frequency of bowel movements diarrhea, constipation, or feeling that the bowel does not empty completely either bright red or very dark blood in the stool stools that are narrower than usual general abdominal discomfort such as frequent gas pains, bloating, fullness, and/or cramps weight loss with no known reason constant tiredness vomiting These symptoms may be caused by colorectal cancer or by other conditions. It is important to check with a doctor if you have symptoms because only a doctor can make a diagnosis. Don't wait to feel pain. Early cancer usually doesn't cause pain. Lowering Your Risk Factors Lower your risk factors where possible. Colon cancer can be prevented if polyps that lead to the cancer are detected and removed. If colon cancer is found in its earliest stages, it is up to 90 percent curable. Tools for Early Detection Beginning at age 50, the following tools are all used for early detection. They can help identify pre-cancerous conditions. If you are younger than 50 and one of your first-degree relatives has had colon cancer, you should consult with your doctor. Tools used for early detection: - A fecal occult blood test, or FOBT, is a test used to check for hidden blood in the stool. Sometimes cancers or polyps can bleed, and FOBT can detect small amounts of bleeding. Newer, genetically-based stool tests are proving to be more accurate than older tests. - A sigmoidoscopy is an examination of the rectum and lower colon -- or sigmoid colon -- using a lighted instrument called a sigmoidoscope. - A colonoscopy is an examination of the rectum and the large intestine (but not the small intestine) using a lighted instrument called a colonoscope. - A virtual colonoscopy, which requires the same preparation as a standard colonoscopy, is done with an external scanning machine as opposed to a device inserted into the colon, although the colon does need to be inflated with gas for proper scanning.

What are the treatments for Colorectal Cancer ? | There are several treatment options for colorectal cancer, although most treatments begin with surgical removal of either the cancerous polyp or section of the colon. The choice of treatment depends on your age and general health, the stage of cancer, whether or not it has spread beyond the colon, and other factors. If tests show that you have cancer, you should talk with your doctor and make treatment decisions as soon as possible. Studies show that early treatment leads to better outcomes. Working With a Team of Specialists A team of specialists often treats people with cancer. The team will keep the primary doctor informed about the patient's progress. The team may include a medical oncologist who is a specialist in cancer treatment, a surgeon, a radiation oncologist who is a specialist in radiation therapy, and others. Before starting treatment, you may want another doctor to review the diagnosis and treatment plan. Some insurance companies require a second opinion. Others may pay for a second opinion if you request it. Clinical Trials for Colorectal Cancer Some colorectal cancer patients take part in studies of new treatments. These studies, called clinical trials, are designed to find out whether a new treatment is safe and effective. Often, clinical trials compare a new treatment with a standard one so that doctors can learn which is more effective. People with colorectal cancer who are interested in taking part in a clinical trial should talk with their doctor. The U.S. National Institutes of Health, through its National Library of Medicine and other Institutes, maintains a database of clinical trials at ClinicalTrials.gov.

What are the treatments for Colorectal Cancer ? | Treatments are available for all patients who have colon cancer. The choice of treatment depends on the size, location, and stage of the cancer and on the patient's general health. Doctors may suggest several treatments or combinations of treatments. Surgery Is the Most Common First Step in a Treatment Regimen The three standard treatments for colon cancer are surgery, chemotherapy, and radiation. Surgery, however, is the most common first step in the treatment for all stages of colon cancer. Surgery is an operation to remove the cancer. A doctor may remove the cancer using several types of surgery. Local Excision If the cancer is found at a very early stage, the doctor may remove it without cutting through the abdominal wall. Instead, the doctor may put a tube up the rectum into the colon and cut the cancer out. This is called a local excision. If the cancer is found in a polyp, which is a small bulging piece of tissue, the operation is called a polypectomy. Colectomy If the cancer is larger, the surgeon will remove the cancer and a small amount of healthy tissue around it. This is called a colectomy. The surgeon may then sew the healthy parts of the colon together. Usually, the surgeon will also remove lymph nodes near the colon and examine them under a microscope to see whether they contain cancer. Colostomy If the doctor is not able to sew the two ends of the colon back together, an opening called a stoma is made on the abdomen for waste to pass out of the body before it reaches the rectum. This procedure is called a colostomy. Sometimes the colostomy is needed only until the lower colon has healed, and then it can be reversed. But if the doctor needs to remove the entire lower colon or rectum, the colostomy may be permanent. Adjuvant Chemotherapy Even if the doctor removes all of the cancer that can be seen at the time of the operation, many patients receive chemotherapy after surgery to kill any cancer cells that are left. Chemotherapy treatment after surgery -- to increase the chances of a cure -- is called adjuvant therapy. Researchers have found that patients who received adjuvant therapy usually survived longer and went for longer periods of time without a recurrence of colon cancer than patients treated with surgery alone. Patients age 70 and older benefited from adjuvant treatment as much as their younger counterparts. In fact, adjuvant therapy is equally as effective -- and no more toxic -- for patients 70 and older as it is for younger patients, provided the older patients have no other serious diseases. Adjuvant chemotherapy is standard treatment for patients whose cancer is operable and who are at high risk for a recurrence of the disease. Most cases of colon cancer occur in individuals age 65 and over. But studies have shown that older patients receive adjuvant chemotherapy less frequently than younger patients. Chemotherapy Chemotherapy is the use of anti-cancer drugs to kill cancer cells. Chemotherapy may be taken by mouth, or it may be put into the body by inserting a needle into a vein or muscle. One form of chemotherapy is called systemic treatment because the drugs enter the bloodstream, travel through the body, and can kill cancer cells throughout the body. The other form of chemotherapy is called targeted therapy because the drug affects only the factors that are causing the cancer and does not perturb the rest of the body. Radiation Therapy Radiation therapy is the use of x-rays or other types of radiation to kill cancer cells and shrink tumors. Most often, doctors use it for patients whose cancer is in the rectum. Doctors may use radiation before surgery to shrink a tumor in the rectum and make it easier to remove. Or, they may use it after surgery to destroy any cancer cells that remain in the treated area. The radiation may come from a machine or from implants placed directly into or near the tumor. Radiation that comes from a machine is called external radiation. Radiation that uses implants is known as internal radiation. Some patients have both kinds of therapy. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the treatments for Colorectal Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Treatments are available for all patients who have colon cancer.

what research (or clinical trials) is being done for Colorectal Cancer ? | Researchers continue to look at new ways to treat, diagnose, and prevent colorectal cancer. Many are testing other types of treatments in clinical trials. Advances in Treatments Studies have found that patients who took the drug Avastin, a targeted chemotherapy drug, with their standard chemotherapy treatment had a longer progression-free survival than those who did not take Avastin, but some studies have indicated that Avastin does not extend life. (The generic name for Avastin is bevacizumab.) Scientists are also working on vaccines therapies and monoclonal antibodies that may improve how patients' immune systems respond to colorectal cancers. Monoclonal antibodies are a single type of antibody that researchers make in large amounts in a laboratory. Surgical techniques have reduced the number of patients needing a permanent colostomy. A colostomy is an opening made in the abdomen for waste to pass out of the body before it reaches the rectum. In many cases, the surgeon can reconnect the healthy parts of the colon back together after removing the cancer. This way, the colon can function just as it did before. The PLCO Trial The National Cancer Institute's Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial, or PLCO Trial, recently provided results about the role of sigmoidoscopy in reducing deaths from colon and rectal cancers. The PLCO trial, involving 148,000 volunteers aged 55 to 74, compared two groups of people over a 10-year period and found that the group that received sigmoidoscopies had fewer deaths from colorectal cancer than those who did not get a sigmoidoscopy. NSAIDs and Polyp Formation Preventing colorectal cancer is a concern of many researchers. Studies have shown that non-steroidal anti-inflammatory drugs (NSAIDs) can keep large-bowel polyps from forming. Bowel polyps can start out benign, or non-cancerous, but can become cancerous. However, the effects that these drugs have on the heart and other parts of the body is of concern, therefore these drugs should only be used for prevention under a doctor's supervision. Genetic Research Genes involved in colorectal cancer continue to be identified and understood. Hereditary nonpolyposis colorectal cancer, or HNPCC, is one condition that causes people in a certain family to develop colorectal cancer at a young age. The discovery of four genes involved with this disease has provided crucial clues about the role of DNA repair in colorectal and other cancers. Scientists are continuing to identify genes associated with colon cancers that run in families. Using traditional screening methods on people from families that carry these genes may be another way to identify cancers at an early stage and cut deaths from colorectal cancer. Genetic screening of people at high risk may become more common in the near future Besides looking at genes in families, researchers in the The Cancer Genome Atlas study looked at the genes of actual colon tumors to better understand the contribution that genes make to cancer. By looking at the genetic composition of the tumor, researchers were able to identify new mutations (changes) in the genes that can lead to cancer, including the genes BRAF and EGRF. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: what research (or clinical trials) is being done for Colorectal Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Researchers continue to look at new ways to treat, diagnose, and prevent colorectal cancer.

What is (are) Colorectal Cancer ? | The body is made up of many types of cells. Normally, cells grow, divide, and produce more cells as needed to keep the body healthy and functioning properly. Sometimes, however, the process goes wrong. Cells become abnormal and form more cells in an uncontrolled way. These extra cells form a mass of tissue, called a growth or tumor.

What are the treatments for Colorectal Cancer ? | Even if the doctor removes all the cancer that can be seen at the time of the operation, many patients receive chemotherapy after surgery to kill any cancer cells that are left. Chemotherapy treatment after surgery -- to increase the chances of a cure -- is called adjuvant therapy. Researchers have found that patients who received adjuvant therapy usually survived longer and went for longer periods of time without a recurrence of colon cancer than patients treated with surgery alone. Patients age 70 and older benefited from adjuvant treatment as much as their younger counterparts.

How to prevent Colorectal Cancer ? | Scientists have done research on chemoprevention -- the use of drugs to prevent cancer from developing in the first place. Most of these studies have looked at people with high risk for the disease (where it runs in families) and not in the general population. For example, researchers have found that anti-inflammatory drugs helped keep intestinal tumors from forming, but serious side effects have been noted so researchers are proceeding cautiously. Studies have shown that non-steroidal anti-inflammatory drugs can keep large bowel polyps from forming. Bowel polyps can start out benign, or non-cancerous, but can become cancerous. Serious cardiac effects of these drugs have been noted so researchers are also proceeding cautiously in recommending these drugs for prevention. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: How to prevent Colorectal Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Scientists have done research on chemoprevention -- the use of drugs to prevent cancer from developing in the first place.

What is (are) Parkinson's Disease ? | A Brain Disorder Parkinson's disease is a brain disorder that leads to shaking, stiffness, and difficulty with walking, balance, and coordination. It affects about half a million people in the United States although the numbers may be much higher. The average age of onset is 60 years, and the risk of developing Parkinson's goes up with age. Parkinson's disease was first described in 1817 by James Parkinson, a British doctor who published a paper on what he called "the shaking palsy." In this paper, he described the major symptoms of the disease that would later bear his name. Four Main Symptoms Parkinson's disease belongs to a group of neurological conditions called movement disorders. The four main symptoms of Parkinson's are: - tremor, or trembling in hands, arms, legs, jaw, or head - rigidity, or stiffness of the limbs and trunk - bradykinesia, or slowness of movement - postural instability, or impaired balance. tremor, or trembling in hands, arms, legs, jaw, or head rigidity, or stiffness of the limbs and trunk bradykinesia, or slowness of movement postural instability, or impaired balance. Parkinson's symptoms usually begin gradually and get worse over time. As the symptoms become more severe, people with the disorder may have difficulty walking, talking, or completing other simple tasks. They also experience non-motor, or movement, symptoms including mental and behavioral changes, sleep problems, depression, memory difficulties, and fatigue. Parkinson's disease not only affects the brain, but the entire body. While the brain involvement is responsible for the core features, other affected locations contribute to the complicated picture of Parkinson's. Parkinson's disease is both chronic, meaning it lasts for a long time, and progressive, meaning its symptoms grow worse over time. It is not contagious. Diagnosis Can Be Difficult About 60,000 Americans are diagnosed with Parkinson's disease each year. However, it's difficult to know exactly how many have it because many people in the early stages of the disease think their symptoms are due to normal aging and do not seek help from a doctor. Also, diagnosis is sometimes difficult because there are no medical tests that can diagnose the disease with certainty and because other conditions may produce symptoms of Parkinson's. For example, people with Parkinson's may sometimes be told by their doctors that they have other disorders, and people with diseases similar to Parkinson's may be incorrectly diagnosed as having Parkinson's. A persons good response to the drug levodopa may support the diagnosis. Levodopa is the main therapy for Parkinsons disease. Who Is at Risk? Both men and women can have Parkinsons disease. However, the disease affects about 50 percent more men than women. While the disease is more common in developed countries, studies also have found an increased risk of Parkinson's disease in people who live in rural areas and in those who work in certain professions, suggesting that environmental factors may play a role in the disorder. Researchers are focusing on additional risk factors for Parkinsons disease. One clear risk factor for Parkinson's is age. The average age of onset is 60 years and the risk rises significantly with advancing age. However, about 5 to 10 percent of people with Parkinson's have "early-onset" disease which begins before the age of 50. Early-onset forms of Parkinson's are often inherited, though not always, and some have been linked to specific gene mutations. Juvenile Parkinsonism In very rare cases, parkinsonian symptoms may appear in people before the age of 20. This condition is called juvenile parkinsonism. It is most commonly seen in Japan but has been found in other countries as well. It usually begins with dystonia (sustained muscle contractions causing twisting movements) and bradykinesia (slowness of movement), and the symptoms often improve with levodopa medication. Juvenile parkinsonism often runs in families and is sometimes linked to a mutated gene. Some Cases Are Inherited Evidence suggests that, in some cases, Parkinsons disease may be inherited. An estimated 15 to 25 percent of people with Parkinson's have a known relative with the disease. People with one or more close relatives who have Parkinson's have an increased risk of developing the disease themselves, but the total risk is still just 2 to 5 percent unless the family has a known gene mutation for the disease. A gene mutation is a change or alteration in the DNA or genetic material that makes up a gene. Researchers have discovered several genes that are linked to Parkinson's disease. The first to be identified was alpha-synuclein or SNCA. Inherited cases of Parkinsons disease are caused by mutations in the LRRK2, PARK2 or parkin, PARK7 or DJ-1, PINK1, or SNCA genes, or by mutations in genes that have not yet been identified. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What is (are) Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> A Brain Disorder Parkinson's disease is a brain disorder that leads to shaking, stiffness, and difficulty with walking, balance, and coordination.

What causes Parkinson's Disease ? | A Shortage of Dopamine Parkinson's disease occurs when nerve cells, or neurons, in an area of the brain that controls movement become impaired and/or die. Normally, these neurons produce an important brain chemical known as dopamine, but when the neurons die or become impaired, they produce less dopamine. This shortage of dopamine causes the movement problems of people with Parkinson's. Dopamine is a chemical messenger, or neurotransmitter. Dopamine is responsible for transmitting signals between the substantia nigra and multiple brain regions. The connection between the substantia nigra and the corpus striatum is critical to produce smooth, purposeful movement. Loss of dopamine in this circuit results in abnormal nerve-firing patterns within the brain that cause impaired movement. Loss of Norepinephrine People with Parkinson's also have loss of the nerve endings that produce the neurotransmitter norepinephrine. Norepinephrine, which is closely related to dopamine, is the main chemical messenger of the sympathetic nervous system. The sympathetic nervous system controls many automatic functions of the body, such as heart rate and blood pressure. The loss of norepinephrine might help explain several of the non-movement features of Parkinson's, such as fatigue, irregular blood pressure, decreased gastric motility or movement of food through the digestive tract, and postural hypotension. Postural hypotension is a sudden drop in blood pressure when a person stands up from a sitting or lying-down position. It may cause dizziness, lightheadedness, and in some cases, loss of balance or fainting. Lewy Bodies in Brain Cells Many brain cells of people with Parkinson's contain Lewy bodies. Lewy bodies are unusual deposits or clumps of the brain protein alpha-synuclein, along with other proteins, which are seen upon microscopic examination of the brain. Researchers do not yet know why Lewy bodies form or what role they play in the development of Parkinson's. The clumps may prevent the cell from functioning normally, or they may actually be helpful, perhaps by keeping harmful proteins "locked up" so the cells can function. Genetic Mutations Although some cases of Parkinson's appear to be hereditary, and a few can be traced to specific genetic mutations, most cases are sporadic. Sporadic means the disease occurs randomly and does not seem to run in families. Many researchers now believe that Parkinson's disease results from a combination of genetic and environmental factors. Scientists have identified several genetic mutations associated with Parkinson's including mutations in the alpha-synuclein gene. They think that many more genes may be linked to the disorder. Studying the genes responsible for inherited cases of Parkinson's can help researchers understand both inherited and sporadic cases. The same genes and proteins that are altered in inherited cases may also be altered in sporadic cases by environmental toxins or other factors. Researchers also hope that discovering genes will help identify new ways of treating Parkinson's. Environmental Toxins Although researchers increasingly recognize the importance of genetics in Parkinson's disease, most believe environmental exposures increase a person's risk of developing the disease. Even in inherited cases, exposure to toxins or other environmental factors may influence when symptoms of the disease appear or how the disease progresses. There are a number of toxins that can cause parkinsonian symptoms in humans. Researchers are pursuing the question of whether pesticides and other environmental factors not yet identified also may cause Parkinson's disease. Viruses are another possible environmental trigger for Parkinson's. Mitochondria and Free Radicals Research suggests that mitochondria may play a role in the development of Parkinson's disease. Mitochondria are the energy-producing components of the cell and are major sources of free radicals. Free radicals are molecules that damage membranes, proteins, DNA, and other parts of the cell. This damage is called oxidative stress. Changes to brain cells caused by oxidative stress, including free radical damage to DNA, proteins, and fats, have been found in people with Parkinson's. Clinical studies now underway test whether agents thought to improve energy metabolism and decrease oxidative stress slow the progression of Parkinson's disease. Recent evidence suggests that mutations in genes linked to Parkinsons disease result in mitochondrial dysfunction. Buildup of Harmful Proteins Other research suggests that the cell's protein disposal system may fail in people with Parkinson's, causing proteins like alpha-synuclein to build up to harmful levels and trigger premature cell death. Additional studies have found that clumps of protein that develop inside brain cells of people with Parkinson's may contribute to the death of nerve cells, or neurons. However, the exact role of the protein deposits remains unknown. These studies also found that inflammation, because of protein accumulation, toxins or other factors, may play a role in the disease. However, the exact role of the protein deposits remains unknown. Researchers are exploring the possibility of vaccine development to decrease or prevent the accumulation of alpha-synuclein. While mitochondrial dysfunction, oxidative stress, inflammation, and many other cellular processes may contribute to Parkinson's disease, scientists still do not know what causes cells that produce dopamine to die. Genes Linked to Parkinsons Researchers have discovered several genes that are linked to Parkinson's disease. The first to be identified was alpha-synuclein or SNCA . Studies have found that Lewy bodies from people with the sporadic form of Parkinson's contain clumps of alpha-synuclein protein. This discovery revealed a possible link between hereditary and sporadic forms of the disease. Other genes linked to Parkinson's include PARK2, PARK7, PINK1, and LRRK2. PARK2, PARK7, and PINK1 cause rare, early-onset forms of the disease. Mutations in the LRRK2 gene are common in specific populations, including in people with Parkinson's in North Africa. Researchers are continuing to study the normal functions and interactions of these genes in order to find clues about how Parkinson's develops. They also have identified a number of other genes and chromosome regions that may play a role in Parkinson's, but the nature of these links is not yet clear. Whole genome wide association studies, or GWAS, of thousands of people with Parkinson's disease are now underway to find gene variants that allow for an increased risk of developing Parkinson's but are not necessarily causes of this disorder by themselves. A recent international study found that two genes containing mutations known to cause rare hereditary forms of Parkinsons disease are also associated with the more common sporadic form of the disease. This finding came from a GWAS which looked at DNA samples of European people who had Parkinsons disease and from those who did not have the disorder. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What causes Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> A Shortage of Dopamine Parkinson's disease occurs when nerve cells, or neurons, in an area of the brain that controls movement become impaired and/or die.

What are the symptoms of Parkinson's Disease ? | Parkinson's disease does not affect everyone the same way. Symptoms of the disorder and the rate of progression differ among people with the disease. Sometimes people dismiss early symptoms of Parkinson's as the effects of normal aging. There are no medical tests to definitively diagnose the disease, so it can be difficult to diagnose accurately. Early Symptoms Early symptoms of Parkinson's disease are subtle and occur gradually. For example, affected people may feel mild tremors or have difficulty getting out of a chair. They may notice that they speak too softly or that their handwriting is slow and looks cramped or small. This very early period may last a long time before the more classic and obvious symptoms appear. Friends or family members may be the first to notice changes in someone with early Parkinson's. They may see that the person's face lacks expression and animation, a condition known as "masked face," or that the person does not move an arm or leg normally. They also may notice that the person seems stiff, unsteady, or unusually slow. As the Disease Progresses As the disease progresses, symptoms may begin to interfere with daily activities. The shaking or tremor may make it difficult to hold utensils steady or read a newspaper. Tremor is usually the symptom that causes people to seek medical help. People with Parkinson's often develop a so-called parkinsonian gait that includes a tendency to lean forward, small quick steps as if hurrying forward (called festination), and reduced swinging of the arms. They also may have trouble initiating or continuing movement, which is known as freezing. Symptoms often begin on one side of the body or even in one limb on one side of the body. As the disease progresses, it eventually affects both sides. However, the symptoms may still be more severe on one side than on the other. Four Primary Symptoms The four primary symptoms of Parkinson's are tremor, rigidity, slowness of movement (bradykinesia), and impaired balance (postural instability). - Tremor often begins in a hand, although sometimes a foot or the jaw is affected first. It is most obvious when the hand is at rest or when a person is under stress. It usually disappears during sleep or improves with a deliberate movement. - Rigidity, or a resistance to movement, affects most people with Parkinson's. It becomes obvious when another person tries to move the individual's arm, such as during a neurological examination. The arm will move only in ratchet-like or short, jerky movements known as "cogwheel" rigidity. - Bradykinesia, or the slowing down and loss of spontaneous and automatic movement, is particularly frustrating because it may make simple tasks somewhat difficult. Activities once performed quickly and easily, such as washing or dressing, may take several hours. - Postural instability, or impaired balance, causes people with Parkinson's to fall easily. They also may develop a stooped posture with a bowed head and droopy shoulders. Tremor often begins in a hand, although sometimes a foot or the jaw is affected first.

Many can be treated with medication or physical therapy. No one can predict which symptoms will affect an individual person, and the intensity of the symptoms varies from person to person. Many people note that prior to experiencing motor problems of stiffness and tremor, they had symptoms of a sleep disorder, constipation, decreased ability to smell, and restless legs. Other symptoms include - depression - emotional changes - difficulty swallowing and chewing - speech changes - urinary problems or constipation - skin problems, sleep problems - dementia or other cognitive problems - orthostatic hypotension (a sudden drop in blood pressure when standing up from a sitting or lying down position) - muscle cramps and dystonia (twisting and repetitive movements) - pain - fatigue and loss of energy - sexual dysfunction. depression emotional changes difficulty swallowing and chewing speech changes urinary problems or constipation skin problems, sleep problems dementia or other cognitive problems orthostatic hypotension (a sudden drop in blood pressure when standing up from a sitting or lying down position) muscle cramps and dystonia (twisting and repetitive movements) pain fatigue and loss of energy sexual dysfunction. A number of disorders can cause symptoms similar to those of Parkinson's disease. People with Parkinson's-like symptoms that result from other causes are sometimes said to have parkinsonism. While these disorders initially may be misdiagnosed as Parkinson's, certain medical tests, as well as response to drug treatment, may help to distinguish them from Parkinson's. Diagnosis Can Be Difficult There are currently no blood, or laboratory tests to diagnose sporadic Parkinson's disease. Diagnosis is based on a person's medical history and a neurological examination, but the disease can be difficult to diagnose accurately. Early signs and symptoms of Parkinson's may sometimes be dismissed as the effects of normal aging. A doctor may need to observe the person for some time until it is clear that the symptoms are consistently present. Improvement after initiating medication is another important hallmark of Parkinson's disease. Doctors may sometimes request brain scans or laboratory tests to rule out other diseases. However, computed tomography (CT) and magnetic resonance imaging (MRI) brain scans of people with Parkinson's usually appear normal. Recently, the FDA (Food and Drug Administration) has approved an imaging technique called DaTscan, which may help to increase accuracy of the diagnosis of Parkinsons disease. Since many other diseases have similar features but require different treatments, it is very important to make an exact diagnosis as soon as possible to ensure proper treatment. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the symptoms of Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Parkinson's disease does not affect everyone the same way.

The arm will move only in ratchet-like or short, jerky movements known as "cogwheel" rigidity. - Bradykinesia, or the slowing down and loss of spontaneous and automatic movement, is particularly frustrating because it may make simple tasks somewhat difficult. Activities once performed quickly and easily, such as washing or dressing, may take several hours. - Postural instability, or impaired balance, causes people with Parkinson's to fall easily. They also may develop a stooped posture with a bowed head and droopy shoulders. Tremor often begins in a hand, although sometimes a foot or the jaw is affected first. It is most obvious when the hand is at rest or when a person is under stress. It usually disappears during sleep or improves with a deliberate movement.

They also may develop a stooped posture with a bowed head and droopy shoulders. Other Symptoms A number of other symptoms may accompany Parkinson's disease. Some are minor; others are not. Many can be treated with medication or physical therapy. No one can predict which symptoms will affect an individual person, and the intensity of the symptoms varies from person to person. Many people note that prior to experiencing motor problems of stiffness and tremor, they had symptoms of a sleep disorder, constipation, decreased ability to smell, and restless legs. Other symptoms include - depression - emotional changes - difficulty swallowing and chewing - speech changes - urinary problems or constipation - skin problems, sleep problems - dementia or other cognitive problems - orthostatic hypotension (a sudden drop in blood pressure when standing up from a sitting or lying down position) - muscle cramps and dystonia (twisting and repetitive movements) - pain - fatigue and loss of energy - sexual dysfunction. depression emotional changes difficulty swallowing and chewing speech changes urinary problems or constipation skin problems, sleep problems dementia or other cognitive problems orthostatic hypotension (a sudden drop in blood pressure when standing up from a sitting or lying down position) muscle cramps and dystonia (twisting and repetitive movements) pain fatigue and loss of energy sexual dysfunction. A number of disorders can cause symptoms similar to those of Parkinson's disease. People with Parkinson's-like symptoms that result from other causes are sometimes said to have parkinsonism. While these disorders initially may be misdiagnosed as Parkinson's, certain medical tests, as well as response to drug treatment, may help to distinguish them from Parkinson's. Diagnosis Can Be Difficult There are currently no blood, or laboratory tests to diagnose sporadic Parkinson's disease. Diagnosis is based on a person's medical history and a neurological examination, but the disease can be difficult to diagnose accurately. Early signs and symptoms of Parkinson's may sometimes be dismissed as the effects of normal aging. A doctor may need to observe the person for some time until it is clear that the symptoms are consistently present. Improvement after initiating medication is another important hallmark of Parkinson's disease. Doctors may sometimes request brain scans or laboratory tests to rule out other diseases. However, computed tomography (CT) and magnetic resonance imaging (MRI) brain scans of people with Parkinson's usually appear normal. Recently, the FDA (Food and Drug Administration) has approved an imaging technique called DaTscan, which may help to increase accuracy of the diagnosis of Parkinsons disease. Since many other diseases have similar features but require different treatments, it is very important to make an exact diagnosis as soon as possible to ensure proper treatment.<|eot_id|> |
What are the treatments for Parkinson's Disease ? | Deep Brain Stimulation Deep brain stimulation, or DBS, is a surgical procedure used to treat a variety of disabling disorders. It is most commonly used to treat the debilitating symptoms of Parkinsons disease. Deep brain stimulation uses an electrode surgically implanted into part of the brain. The electrodes are connected by a wire under the skin to a small electrical device called a pulse generator that is implanted in the chest. The pulse generator and electrodes painlessly stimulate the brain in a way that helps to stop many of the symptoms of Parkinson's such as tremor, bradykinesia, and rigidity. DBS is primarily used to stimulate one of three brain regions: the subthalamic nucleus, the globus pallidus, or the thalamus. Researchers are exploring optimal generator settings for DBS, whether DBS of other brain regions will also improve symptoms of Parkinsons disease, and also whether DBS may slow disease progression. Deep brain stimulation usually reduces the need for levodopa and related drugs, which in turn decreases dyskinesias and other side effects. It also helps to relieve on-off fluctuation of symptoms. People who respond well to treatment with levodopa tend to respond well to DBS. Unfortunately, older people who have only a partial response to levodopa may not improve with DBS. Complementary and Supportive Therapies A wide variety of complementary and supportive therapies may be used for Parkinson's disease. Among these therapies are standard physical, occupational, and speech therapies, which help with gait and voice disorders, tremors and rigidity, and decline in mental functions. Other supportive therapies include diet and exercise. Diet At this time there are no specific vitamins, minerals, or other nutrients that have any proven therapeutic value in Parkinson's disease. Some early reports have suggested that dietary supplements might protect against Parkinson's. Also, a preliminary clinical study of a supplement called coenzyme Q10 suggested that large doses of this substance might slow disease progression in people with early-stage Parkinson's. This supplement is now being tested in a large clinical trial. Other studies are being conducted to find out if caffeine, antioxidants, nicotine, and other dietary factors may help prevent or treat the disease. While there is currently no proof that any specific dietary factor is beneficial, a normal, healthy diet can promote overall well-being for people with Parkinson's disease, just as it would for anyone else. A high protein meal, however, may limit levodopa's effectiveness because for a time afterwards less levodopa passes through the blood-brain barrier. Exercise Exercise can help people with Parkinson's improve their mobility and flexibility. It can also improve their emotional well-being. Exercise may improve the brain's dopamine production or increase levels of beneficial compounds called neurotrophic factors in the brain. Other Therapies Other complementary therapies include massage therapy, yoga, tai chi, hypnosis, acupuncture, and the Alexander technique, which improves posture and muscle activity. There have been limited studies suggesting mild benefits from some of these therapies, but they do not slow Parkinson's disease and to date there is no convincing evidence that they help. However, this remains an active area of investigation. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the treatments for Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Deep Brain Stimulation Deep brain stimulation, or DBS, is a surgical procedure used to treat a variety of disabling disorders.

what research (or clinical trials) is being done for Parkinson's Disease ? | In recent years, research on Parkinson's has advanced to the point that halting the progression of the disease, restoring lost function, and even preventing the disease are all considered realistic goals. While the goal of preventing Parkinson's disease may take years to achieve, researchers are making great progress in understanding and treating it. Genetics Research One of the most exciting areas of Parkinson's research is genetics. Studying the genes responsible for inherited cases can help researchers understand both inherited and sporadic cases of the disease. Identifying gene defects can also help researchers - understand how Parkinson's occurs - develop animal models that accurately mimic the death of nerve cells in humans - identify new approaches to drug therapy - improve diagnosis. understand how Parkinson's occurs develop animal models that accurately mimic the death of nerve cells in humans identify new approaches to drug therapy improve diagnosis. Researchers funded by the National Institute of Neurological Disorders and Stroke are gathering information and DNA samples from hundreds of families with members who have Parkinson's and are conducting large-scale studies to identify gene variants that are associated with increased risk of developing the disease. They are also comparing gene activity in Parkinson's with gene activity in similar diseases such as progressive supranuclear palsy. In addition to identifying new genes for Parkinson's disease, researchers are trying to learn about the function of genes known to be associated with the disease, and about how gene mutations cause disease. Effects of Environmental Toxins Scientists continue to study environmental toxins such as pesticides and herbicides that can cause Parkinson's symptoms in animals. They have found that exposing rodents to the pesticide rotenone and several other agricultural chemicals can cause cellular and behavioral changes that mimic those seen in Parkinson's. Role of Lewy Bodies Other studies focus on how Lewy bodies form and what role they play in Parkinson's disease. Some studies suggest that Lewy bodies are a byproduct of a breakdown that occurs within nerve cells, while others indicate that Lewy bodies are protective, helping neurons "lock away" abnormal molecules that might otherwise be harmful. Identifying Biomarkers Biomarkers for Parkinson's -- measurable characteristics that can reveal whether the disease is developing or progressing -- are another focus of research. Such biomarkers could help doctors detect the disease before symptoms appear and improve diagnosis of the disease. They also would show if medications and other types of therapy have a positive or negative effect on the course of the disease. The National Disorders of Neurological Disorders and Stroke has developed an initiative, the Parkinsons Disease Biomarkers Identification Network (PD-BIN), designed specifically to address these questions and to discover and validate biomarkers for Parkinsons disease. Transcranial Therapies Researchers are conducting many studies of new or improved therapies for Parkinson's disease. Studies are testing whether transcranial electrical polarization (TEP) or transcranial magnetic stimulation (TMS) can reduce the symptoms of the disease. In TEP, electrodes placed on the scalp are used to generate an electrical current that modifies signals in the brain's cortex. In TMS, an insulated coil of wire on the scalp is used to generate a brief electrical current. Drug Discovery A variety of new drug treatments for Parkinson's disease are in clinical trials. Several MAO-B inhibitors including selegiline, lazabemide, and rasagiline, are being tested to determine if they have neuroprotective effects in people with Parkinsons disease. The National Institute of Neurological Disorders and Stroke has launched a broad effort to find drugs to slow the progression of Parkinson's disease, called NET-PD or NIH Exploratory Trials in Parkinson's Disease. The first studies tested several compounds; one of these, creatine, is now being evaluated in a larger clinical trial. The NET-PD investigators are testing a highly purified form of creatine, a nutritional supplement, to find out if it slows the decline seen in people with Parkinson's. Creatine is a widely used dietary supplement thought to improve exercise performance. Cellular energy is stored in a chemical bond between creatine and a phosphate. More recently, NET-PD has initiated pilot studies to test pioglitazone, a drug that has been shown to stimulate mitochondrial function. Because mitochondrial function may be less active in Parkinsons disease, this drug may protect vulnerable dopamine neurons by boosting mitochondrial function. Cell Implantation Another potential approach to treating Parkinson's disease is to implant cells to replace those lost in the disease. Starting in the 1990s, researchers conducting a controlled clinical trial of fetal tissue implants tried to replace lost dopamine-producing nerve cells with healthy ones from fetal tissue in order to improve movement and the response to medications. While many of the implanted cells survived in the brain and produced dopamine, this therapy was associated with only modest functional improvements, mostly in patients under the age of 60. Some of the people who received the transplants developed disabling dyskinesias that could not be relieved by reducing anti-parkinsonian medications. Stem Cells Another type of cell therapy involves stem cells. Some stem cells derived from embryos can develop into any kind of cell in the body, while others, called progenitor cells, are less flexible. Researchers are developing methods to improve the number of dopamine-producing cells that can be grown from embryonic stem cells in culture. Other researchers are also exploring whether stem cells from adult brains might be useful in treating Parkinson's disease. Recent studies suggest that some adult cells from skin can be reprogrammed to an embryonic-like state, resulting in induced pluripotent stem cells (iPSC) that may someday be used for treatment of Parkinsons. In addition, development and characterization of cells from people with sporadic or inherited Parkinsons may reveal information about cellular mechanisms of disease and identify targets for drug development. Gene Therapy A number of early clinical trials are now underway to test whether gene therapy can improve Parkinson's disease. Genes which are found to improve cellular function in models of Parkinson's are inserted into modified viruses. The genetically engineered viruses are then injected into the brains of people with Parkinson's disease. Clinical studies have focused on the therapeutic potential of neurotrophic factors, including GDNF and neurturin, and enzymes that produce dopamine. These trials will test whether the viruses, by lending to the production of the protective gene product, improve symptoms of Parkinson's over time. The National Institute of Neurological Disorders and Stroke also supports the Morris K. Udall Centers of Excellence for Parkinson's Disease Research program . These Centers, located across the USA, study cellular mechanisms underlying Parkinsons disease, identify and characterize disease-associated genes, and discover and develop potential therapeutic targets. The Centers' multidisciplinary research environment allows scientists to take advantage of new discoveries in the basic, translational and clinical sciences that could lead to clinical advances for Parkinsons disease. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: what research (or clinical trials) is being done for Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> In recent years, research on Parkinson's has advanced to the point that halting the progression of the disease, restoring lost function, and even preventing the disease are all considered realistic goals.

What are the symptoms of Parkinson's Disease ? | Parkinson's belongs to a group of neurological conditions called movement disorders. The four main symptoms of Parkinson's disease are: - tremor, or trembling in hands, arms, legs, jaw, or head - rigidity, or stiffness of the limbs and trunk - bradykinesia, or slowness of movement - postural instability, or impaired balance. tremor, or trembling in hands, arms, legs, jaw, or head rigidity, or stiffness of the limbs and trunk bradykinesia, or slowness of movement postural instability, or impaired balance. Other symptoms include depression, emotional changes, difficulty swallowing, speech changes, urinary problems, sleep problems, and dementia and other cognitive problems. Parkinson's symptoms usually begin gradually and get worse over time. As the symptoms become more severe, people with the disorder may have difficulty walking, talking, or completing other simple tasks. They also experience non-motor, or movement, symptoms including mental and behavioral changes, sleep problems, depression, memory difficulties, and fatigue. Parkinson's disease not only affects the brain, but the entire body. While the brain involvement is responsible for the core features, other affected locations contribute to the complicated picture of Parkinson's. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the symptoms of Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Parkinson's belongs to a group of neurological conditions called movement disorders.

Who is at risk for Parkinson's Disease? ? | About 60,000 Americans are diagnosed with Parkinson's disease each year. The disease strikes about 50 percent more men than women. The average age of onset is 60 years, and the risk of developing the disease increases with age. Parkinson's disease is also more common in developed countries, possibly because of increased exposure to pesticides or other environmental toxins. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: Who is at risk for Parkinson's Disease? ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> About 60,000 Americans are diagnosed with Parkinson's disease each year.

What causes Parkinson's Disease ? | Parkinson's disease occurs when nerve cells, or neurons, in an area of the brain that controls movement die or become impaired. Normally, these neurons produce an important brain chemical known as dopamine, but once the neurons become impaired, they produce less dopamine and eventually die. It is this shortage of dopamine that causes the movement problems of people with Parkinson's. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What causes Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Parkinson's disease occurs when nerve cells, or neurons, in an area of the brain that controls movement die or become impaired.

How to diagnose Parkinson's Disease ? | There are currently no blood or laboratory tests to diagnose sporadic Parkinson's disease. Diagnosis is based on a person's medical history and a neurological examination, but the disease can be difficult to diagnose accurately. Doctors may sometimes request brain scans or laboratory tests in order to rule out other diseases. However, computed tomography (CT) and magnetic resonance imaging (MRI) brain scans of people with Parkinson's usually appear normal. Recently, the FDA (Food and Drug Administration) has approved an imaging technique called DaTscan, which may help to increase accuracy of the diagnosis of Parkinsons disease. Since many other diseases have similar features but require different treatments, it is very important to make an exact diagnosis as soon as possible to ensure proper treatment. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: How to diagnose Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> There are currently no blood or laboratory tests to diagnose sporadic Parkinson's disease.

What is (are) Parkinson's Disease ? | The main therapy for Parkinson's disease is the drug levodopa, also called L-dopa. It is a simple chemical found naturally in plants and animals. Nerve cells use levodopa to make dopamine to replenish the brain's supply. Levodopa helps to reduce tremors and other symptoms of Parkinson's disease during the early stages of the disease. It allows most people with Parkinson's to extend the period of time in which they can lead relatively normal, productive lives. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What is (are) Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> The main therapy for Parkinson's disease is the drug levodopa, also called L-dopa. It is a simple chemical found naturally in plants and animals. Nerve cells use levodopa to make dopamine to replenish the brain's supply. Levodopa helps to reduce tremors and other symptoms of Parkinson's disease during the early stages of the disease. It allows most people with Parkinson's to extend the period of time in which they can lead relatively normal, productive lives.<|eot_id|> |
What is (are) Parkinson's Disease ? | Carbidopa is a drug that is usually given along with levodopa. It delays the body's conversion of levodopa into dopamine until the levodopa reaches the brain. This prevents or reduces some of the side effects that often accompany levodopa therapy. Carbidopa also reduces the amount of levodopa needed. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What is (are) Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Carbidopa is a drug that is usually given along with levodopa.

What are the treatments for Parkinson's Disease ? | Yes. Other medications available to treat some symptoms and stages of Parkinson's disease include direct dopamine agonists, MAO-B inhibitors, COMT inhibitors, an anti-viral drug, and anticholinergics. Direct dopamine agonists are drugs that mimic the role of dopamine in the brain. They can be used in the early stages of the disease, or later on to give a more prolonged and steady dopaminergic effect in people who experience "wearing off" or "on-off" effects from taking the drug. Dopamine agonists are generally less effective than levodopa in controlling rigidity and bradykinesia. They can cause confusion in older adults. MAO-B inhibitors are another class of drugs that can reduce the symptoms of Parkinson's by causing dopamine to build up in surviving nerve cells. COMT inhibitors prolong the effects of levodopa by preventing the breakdown of dopamine. COMT inhibitors can usually make it possible to reduce a person's dose of levodopa. Amantadine, an old antiviral drug, can help reduce Parkinson's symptoms in the early stages of the disease, and again in later stages to treat dyskinesias. Anticholinergics can help reduce tremors and muscle rigidity. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the treatments for Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Yes.

What are the symptoms of Parkinson's Disease ? | Doctors may prescribe a variety of medications to treat the non-motor symptoms of Parkinson's disease, such as depression and anxiety. Hallucinations, delusions, and other psychotic symptoms may be caused by some drugs prescribed for Parkinson's. Therefore, reducing or stopping those Parkinson's medications may make these symptoms of psychosis go away. A variety of treatment options, including medications, also are available to treat orthostatic hypotension, the sudden drop in blood pressure that occurs upon standing. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the symptoms of Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Doctors may prescribe a variety of medications to treat the non-motor symptoms of Parkinson's disease, such as depression and anxiety.

What is (are) Parkinson's Disease ? | Deep brain stimulation, or DBS, is a surgical procedure used to treat a variety of disabling disorders. It is most commonly used to treat the debilitating symptoms of Parkinsons disease. Deep brain stimulation uses an electrode surgically implanted into part of the brain. The electrodes are connected under the skin to a small electrical device called a pulse generator, implanted in the chest. The generator and electrodes painlessly stimulate the brain to help stop many Parkinson's symptoms such as tremor, bradykinesia, and rigidity. DBS is primarily used to stimulate one of three brain regions: the subthalamic nucleus, the globus pallidus, or the thalamus. Researchers are exploring optimal generator settings for DBS, whether DBS of other brain regions will also improve symptoms of Parkinsons disease, and also whether DBS may slow disease progression. Deep brain stimulation usually reduces the need for levodopa and related drugs, which in turn decreases dyskinesias and other side effects. It also helps to relieve "on-off" fluctuation of symptoms. People who respond well to treatment with levodopa, even if only for a short period, tend to respond well to DBS. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What is (are) Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Deep brain stimulation, or DBS, is a surgical procedure used to treat a variety of disabling disorders.

what research (or clinical trials) is being done for Parkinson's Disease ? | Genetics is one of the most exciting areas of Parkinson's disease research. Studying the genes responsible for inherited cases can help researchers understand both inherited and sporadic cases of the disease. Sporadic means the disease occurs randomly and does not seem to run in families. Identifying gene defects can also help researchers - understand how the disease occurs - develop animal models that accurately mimic the death of nerve cells in human Parkinson's disease - identify new drug targets - improve diagnosis. understand how the disease occurs develop animal models that accurately mimic the death of nerve cells in human Parkinson's disease identify new drug targets improve diagnosis. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: what research (or clinical trials) is being done for Parkinson's Disease ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Genetics is one of the most exciting areas of Parkinson's disease research.

What is (are) Leukemia ? | Leukemia is a cancer of the blood cells. It is the most common type of blood cancer and affects 10 times as many adults as children. Most people diagnosed with leukemia are over 50 years old. Leukemia Starts in Bone Marrow Leukemia usually begins in the bone marrow, the soft material in the center of most bones where blood cells are formed. The bone marrow makes three types of blood cells, and each type has a special function. - White blood cells fight infection and disease. - Red blood cells carry oxygen throughout the body. - Platelets help control bleeding by forming blood clots. White blood cells fight infection and disease. Red blood cells carry oxygen throughout the body. Platelets help control bleeding by forming blood clots. In people with leukemia, the bone marrow produces abnormal white blood cells, called leukemia cells. At first, leukemia cells function almost normally. But over time, as more leukemia cells are produced, they may crowd out the healthy white blood cells, red blood cells, and platelets. This makes it difficult for the blood to carry out its normal functions. There are four common types of adult leukemia. Two are chronic, meaning they get worse over a longer period of time. The other two are acute, meaning they get worse quickly. - chronic lymphocytic leukemia - chronic myeloid leukemia - acute myeloid leukemia - acute lymphocytic leukemia chronic lymphocytic leukemia chronic myeloid leukemia acute myeloid leukemia acute lymphocytic leukemia Chronic and Acute Leukemia Chronic lymphocytic leukemia, chronic myeloid leukemia, and acute myeloid leukemia are diagnosed more often in older adults. Of these, chronic lymphocytic leukemia is the most common. Acute lymphocytic leukemia is found more often in children. The symptoms for each type of leukemia differ but may include fevers, frequent infections, fatigue, swollen lymph nodes, weight loss, and bleeding and bruising easily. However, such symptoms are not sure signs of leukemia. An infection or another problem also could cause these symptoms. Only a doctor can diagnose and treat the problem.

Other Cancers That Affect Blood Cells Myeloma and lymphoma are other types of cancer that affect blood cells, but these cancer cells are rarely found in the blood stream. Myeloma is the second most common form of blood cancer, and it affects plasma cells, a type of white blood cell that is found in the bone marrow. Lymphoma accounts for about five percent of all the types of cancer in the United States. It starts in the lymphatic system, which is part of the body's immune system. Both myeloma and lymphoma are more common among older adults and occur more often in men than women. Learn more about myeloma. Many Treatments Are Available There are many methods available to treat acute and chronic leukemia, and there are many new treatments being developed that are rapidly changing how numerous types of leukemia are treated. The types of treatments depend on the specific disease and how best to treat it. Some people receive a combination of treatments. Acute leukemia usually needs to be treated right away. But there are many different kinds of acute leukemia. Some respond well to treatment and can be cured in some cases, while others are more difficult to treat. Treatment for chronic leukemia can often control the disease and its symptoms and there are new treatments being developed that may prolong survival.

Who is at risk for Leukemia? ? | In many cases, no one knows why some people develop leukemia and others do not. However, scientists have identified some risk factors for the disease. A risk factor is anything that increases a person's chances of developing a disease. Most people who have known risk factors do not get leukemia, while many who do get the disease have none of these risk factors. Risk Factors Studies have identified the following risk factors for leukemia. - older age - male - white - working with certain chemicals - smoking - exposure to very high levels of radiation - certain health conditions - past treatment with chemotherapy or radiation therapy. older age male white working with certain chemicals smoking exposure to very high levels of radiation certain health conditions past treatment with chemotherapy or radiation therapy. More than 65 percent of people diagnosed with leukemia are over 55. Disorders and Genetic Diseases Certain disorders and genetic diseases, such as Down syndrome, may increase the risk of leukemia. About 3 out of 10 people with a blood disorder known as myelodysplastic syndrome develop acute myeloid leukemia. In this disorder, as in leukemia, abnormal cells are formed in the bone marrow and too few healthy blood cells enter the bloodstream. Radiation Exposure People exposed to very high levels of radiation, such as the atomic bomb blast in Hiroshima, Japan or nuclear power plant accidents, also are at risk of developing leukemia. Studies of atomic blasts have estimated that survivors have a five and a half times greater risk of developing leukemia than the general public. Cancer Treatments Chemotherapy and radiation therapy have been helpful to a lot of people in the treatment of many forms of cancer, and indeed are often lifesaving. However, these therapies have been linked to the development of second cancers, including leukemia, many years after treatment, particularly in people who received intensive therapy early in their lives. Chemotherapy for a first cancer is a stronger risk factor for developing leukemia later than is radiation therapy. The combination of chemotherapy and radiation can significantly increase the risk of leukemia after a first cancer. Powerful cancer-fighting chemotherapy drugs, known as alkylating agents and epipodophyllotoxins, have been associated with leukemia. The dose given and length of treatment as well as other factors may contribute to a person's risk of developing leukemia. Acute myeloid leukemia is the most common type of cancer that has been linked to chemotherapy treatment. Radiation therapy may increase a person's chance of developing leukemia. Several factors influence this risk, such as the dose of radiation administered. A person's age at the time of therapy does not seem to be a risk factor for leukemia. Recently, researchers have gained a much greater understanding of the risk of second cancers due to earlier treatment exposures. They have been able to limit the effective doses given in primary cases so as to reduce the risk of a recurrence or second cancer. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: Who is at risk for Leukemia? ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> In many cases, no one knows why some people develop leukemia and others do not.

What are the symptoms of Leukemia ? | During the early stages of leukemia, there may be no symptoms. Many of the symptoms of leukemia don't become apparent until a large number of normal blood cells are crowded out by leukemia cells. Symptoms of Chronic and Acute Leukemia In chronic leukemia, symptoms develop gradually and, in the beginning, are generally not as severe as in acute leukemia. Chronic leukemia is usually found during a routine doctor's exam before symptoms are present. When symptoms appear, they generally are mild at first and gradually get worse, but sometimes they don't worsen until many years after an initial diagnosis. Recently, researchers discovered that abnormal white blood cells can be present in the blood of chronic lymphocytic leukemia patients a number of years before a diagnosis. This finding may lead to a better understanding of the cellular changes that occur in the earliest stages of the disease and how the disease progresses. In acute leukemia, symptoms usually appear and get worse quickly. People with this disease usually go to their doctor because they feel sick. White Blood Cell Levels May Be High People with leukemia may have very high levels of white blood cells, but because the cells are abnormal, they are unable to fight infection. Therefore, patients may develop frequent fevers or infections. A shortage of red blood cells, called anemia, can cause a person to feel tired. Not having enough blood platelets may cause a person to bleed and bruise easily. Some symptoms depend on where leukemia cells collect in the body. Leukemia cells can collect in many different tissues and organs, such as the digestive tract, kidneys, lungs, lymph nodes, or other parts of the body, including the eyes, brain, and testicles. Other Common Symptoms Other common symptoms of leukemia include headache, weight loss, pain in the bones or joints, swelling or discomfort in the abdomen (from an enlarged spleen), and swollen lymph nodes, especially in the neck or armpit. Symptoms of acute leukemia may include vomiting, confusion, loss of muscle control, and seizures. Some of the symptoms of leukemia are similar to those caused by the flu or other common diseases, so these symptoms are not sure signs of leukemia. It is important to check with your doctor if you have these symptoms. Only a doctor can diagnose and treat leukemia. Diagnosing Leukemia: Physical Exam, Blood Tests, Biopsy To find the cause of leukemia symptoms, the doctor will ask about medical history and conduct a physical exam. During the exam, the doctor will check for signs of disease such as lumps, swelling in the lymph nodes, spleen, and liver, or anything else that seems unusual. The doctor will need to do blood tests that check the levels and types of blood cells and look for changes in the shape of blood cells. The doctor also may look at certain factors in the blood to see if leukemia has affected other organs such as the liver or kidneys. Even if blood tests suggest leukemia, the doctor may look for signs of leukemia in the bone marrow by doing a biopsy before making a diagnosis. A biopsy is a procedure where a small amount of bone marrow is removed from a bone. A pathologist examines the sample under a microscope to look for abnormal cells. There are two ways the doctor can obtain bone marrow. In a bone marrow aspiration, marrow is collected by inserting a needle into the hipbone or another large bone and removing a small amount of bone marrow. A bone marrow biopsy is performed with a larger needle and removes bone marrow and a small piece of bone. If Leukemia Cells Are Found If leukemia cells are found in the bone marrow sample, the doctor may perform more tests to determine if the disease has spread to other parts of the body. The doctor may collect a sample of the fluid around the brain and spinal cord by performing a spinal tap and checking for leukemia cells or other signs of problems. Computed tomography (CT) scans, and ultrasounds are tests used to determine if leukemia has spread from the bone marrow. These tests produce pictures of the inside of the body. With these tests, the doctor looks for abnormalities such as enlarged organs or signs of infection. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the symptoms of Leukemia ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> During the early stages of leukemia, there may be no symptoms.

What are the treatments for Leukemia ? | There are many treatment options for people with leukemia. The choice of treatment depends on your age and general health, the type of leukemia you have, whether or not it has spread outside the bone marrow, and other factors. If tests show that you have leukemia, you should talk with your doctor and make treatment decisions as soon as possible, although many patients with chronic lymphocytic leukemia do not require treatment for many years. Working With a Team of Specialists A team of specialists often treats people with leukemia. The team will keep the primary doctor informed about the patient's progress. The team may include a hematologist who is a specialist in blood and blood-forming tissues, a medical oncologist who is a specialist in cancer treatment, and a radiation oncologist who is a specialist in radiation therapy. Before starting treatment, you may want another doctor to review the diagnosis and treatment plan. Some insurance companies require a second opinion. Others may pay for a second opinion if you or your doctor requests it. Clinical Trials for Leukemia Some leukemia patients take part in studies of new treatments. These studies, called clinical trials, are designed to find out whether a new treatment is safe and effective and better than current treatments. Talk to your doctor if you are interested in taking part in a clinical trial. The U.S. National Institutes of Health, through its National Library of Medicine and other Institutes, maintains a database of clinical trials at ClinicalTrials.gov.

What are the treatments for Leukemia ? | Unlike other types of cancer, leukemia isn't a tumor that your doctor can surgically remove. Leukemia cells are produced in the bone marrow and travel throughout the body. The Goal of Treatment The goal of treatment for leukemia is to destroy the leukemia cells and allow normal cells to form in the bone marrow. Depending on the type and extent of the disease, patients may have chemotherapy, biological therapy, radiation therapy, or stem cell transplantation. Some patients receive a combination of treatments. Treatment depends on a number of factors, including the type of leukemia, the patient's age and general health, whether leukemia cells are present in the fluid around the brain or spinal cord, and whether the leukemia has been treated before. It also may depend on certain features of the leukemia cells and the patient's symptoms. Acute Leukemia or Chronic Leukemia? If a person has acute leukemia, they will need treatment right away. The purpose of treatment is to stop the rapid growth of leukemia cells and to bring about remission, meaning the cancer is under control. In many cases, a person will continue treatment after signs and symptoms disappear to prevent the disease from coming back. Some people with acute leukemia can be cured. Learn more about treatments for acute myeloid leukemia. Learn more about treatments for chronic lymphocytic leukemia. Chronic leukemia may not need to be treated until symptoms appear. Treatment can often control the disease and its symptoms. Types of Treatments Some, but not all, forms of treatment for leukemia include - chemotherapy - biological therapy - radiation therapy. chemotherapy biological therapy radiation therapy. Chemotherapy Chemotherapy uses drugs to kill cancer cells. This a common treatment for some types of leukemia. Chemotherapy may be taken by mouth in pill form, by injection directly into a vein, or through a catheter. If leukemia cells are found in the fluid around the brain or spinal cord, the doctor may inject drugs directly into the fluid to ensure that the drugs reach the leukemia cells in the brain. Biological Therapy Biological therapy uses special substances that improve the body's natural defenses against cancer. Some patients with chronic lymphocytic leukemia receive monoclonal antibodies, which are man-made proteins that can identify leukemia cells. Monoclonal antibodies bind to the cells and assist the body in killing them. Although monoclonal antibodies are being used to treat leukemia, researchers are studying more innovative ways to use them in treatment. Some antibodies are used alone to try to prompt the immune system to attack leukemia cells. Other antibodies are attached to substances that can deliver poison to cancer cells. These modified antibodies, called immunotoxins, deliver the toxins directly to the cancer cells. Lately, precision medicine trials have shown evidence that single targeted therapies taken in pill form can prolong survival. Radiation Therapy Radiation therapy uses high-energy X-rays to destroy cancer cells. A machine outside the body directs high-energy beams at the spleen, the brain, or other parts of the body where leukemia cells have collected. Radiation therapy is used primarily to control disease in bones that are at risk of fracture or at sites that are causing pain. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the treatments for Leukemia ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Unlike other types of cancer, leukemia isn't a tumor that your doctor can surgically remove.

what research (or clinical trials) is being done for Leukemia ? | Researchers are conducting clinical trials in many parts of the country. Clinical trials test an intervention such as a drug, therapy, medical device, or behavior in many people to see if it is safe and effective. Clinical trials already have led to advances, and researchers continue to search for more effective ways to treat and diagnose leukemia. They are studying various drugs, immunotherapy, targeted therapies, and other types of treatments. They are also studying the effectiveness of using combinations of treatments. Most importantly, researchers are gaining a greater understanding of the genes that are mutated in many types of leukemia and are developing targeted treatments to directly attack the mutations. One prime example is in acute myeloid leukemia (AML) where researchers have identified several genes that predict better or worse outcomes and are working to develop drugs targeted at these genes. Drug Research The drug imatinib (Gleevec) is important in the treatment of chronic myeloid leukemia. Imatinib targets an abnormal protein that is present in most leukemia cells. By blocking the abnormal protein, imatinib kills the leukemia cells, but it does not kill normal cells. However, imatinib stops working in some people with leukemia because the cells become resistant. Fortunately, two drugs, dasatinib (Sprycel) and nilotinib (Tasigna), are now used to treat people who stop responding to imatinib. These drugs work against the same abnormal protein targeted by imatinib, but in different ways. Immunotherapy Immunotherapy is a treatment that uses immune cells or antibodies to fight leukemia or stop it from getting worse. The idea is to zero in on leukemia cells so the treatment is less toxic to normal cells. Recently developed immunotherapies are showing real promise in a number of forms of leukemia. Vaccine Research Leukemia vaccines are not vaccines in the way that most people think of them. Unlike most vaccines, which help prevent diseases, leukemia vaccines are used to treat someone who already has cancer. A vaccine introduces a molecule called an antigen into the body. The immune system recognizes the antigen as a foreign invader and attacks it. Gene Therapy Gene therapy -- replacing, manipulating, or supplementing nonfunctional genes with healthy genes -- is being explored for treatment of leukemia. It is being studied as a way to stimulate a patient's immune system to kill leukemia cells and also to interfere with the production of proteins that cause cells to become cancerous.

What are the treatments for Leukemia ? | Researchers are studying various drugs, immunotherapies, and other types of treatments. Because leukemia is a complicated disease, researchers are also studying the effectiveness of using combinations of treatments. Following are a few examples of some areas of current research. The drug imatinib (Gleevec) is important in the treatment of chronic myeloid leukemia. However, imatinib stops working in some people with leukemia because the cells become resistant. Fortunately, two drugs, dasatinib (Sprycel) and nilotinib (Tasigna), are being used to treat people who stop responding to imatinib. Both are approved by the FDA for use in patients. These drugs work against the same abnormal protein targeted by imatinib, but in different ways. Gene therapy -- replacing, manipulating, or supplementing nonfunctional genes with healthy genes -- is being explored for treatment of leukemia.

What is (are) Lung Cancer ? | How Tumors Form The body is made up of many types of cells. Normally, cells grow, divide, and produce more cells as needed to keep the body healthy and functioning properly. Sometimes, however, the process goes wrong and cells become abnormal, forming more cells in an uncontrolled way. These extra cells form a mass of tissue, called a growth or tumor. Tumors can be benign, which means not cancerous, or malignant, which means cancerous. Lung cancer occurs when a tumor forms in the tissue of the lung. The Leading Cause of Cancer Death Lung cancer is the leading cause of cancer death in men and women in the United States. Experts estimate that over 200,000 new cases of lung cancer will be diagnosed each year slightly more cases in men than women. Over 150,000 Americans die of the disease each year. Lung cancer occurs most often between the ages of 55 and 65. (Watch the videos on this page to learn more about lung cancer. To enlarge the videos, click the brackets in the lower right-hand corner of the video screen. To reduce the videos, press the Escape (Esc) button on your keyboard.) Two Major Types of Lung Cancer There are two major types of lung cancer -- non-small cell lung cancer and small cell lung cancer. Each type of lung cancer grows and spreads in different ways, and each is treated differently. - Non-small cell lung cancer is more common than small cell lung cancer. - Small cell lung cancer grows more quickly and is more likely to spread to other organs in the body. Non-small cell lung cancer is more common than small cell lung cancer. Small cell lung cancer grows more quickly and is more likely to spread to other organs in the body. Learn more about non-small cell lung cancer. Learn more about small cell lung cancer. Lung Cancer Can Spread Lung cancer may spread to the lymph nodes or other tissues in the chest, including the lung opposite to where it originated. It may also spread to other organs of the body, such as the bones, brain, or liver. When cancer spreads from its original location in the lung to another part of the body such as the brain, it is called metastatic lung cancer, not brain cancer. Doctors sometimes call this distant disease. Smoking and Lung Cancer Lung cancer would occur much less often if people did not smoke. The good news is that smoking is not as popular as it used to be. In 1965 about 42 percent of all adults smoked, but as of 2012, slightly less than 17 percent of people 18 and older smoked cigarettes. Also, since the 1990s there has been a steady drop in lung cancer deaths among men, mainly because fewer men are smoking, and since the turn of the century, lung cancer deaths in women have been slowly declining. Cigarette smoking rates had been dropping steadily in the 1990s and had started to level off at the start of the 21st century but the latest figures show a continued decline. The bad news is that other forms of tobacco use have shown some revival, but mainly in younger populations. The bad news is that smoking rates, which were dropping, have stopped declining in recent years. Smoking by young adults actually increased by 73 percent in the 1990s but has shown a downturn or leveling off in the past few years. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What is (are) Lung Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> How Tumors Form The body is made up of many types of cells. Normally, cells grow, divide, and produce more cells as needed to keep the body healthy and functioning properly. Sometimes, however, the process goes wrong and cells become abnormal, forming more cells in an uncontrolled way. These extra cells form a mass of tissue, called a growth or tumor. Tumors can be benign, which means not cancerous, or malignant, which means cancerous. Lung cancer occurs when a tumor forms in the tissue of the lung. The Leading Cause of Cancer Death Lung cancer is the leading cause of cancer death in men and women in the United States. Experts estimate that over 200,000 new cases of lung cancer will be diagnosed each year slightly more cases in men than women. Over 150,000 Americans die of the disease each year. Lung cancer occurs most often between the ages of 55 and 65. (Watch the videos on this page to learn more about lung cancer.

Two Major Types of Lung Cancer There are two major types of lung cancer -- non-small cell lung cancer and small cell lung cancer. Each type of lung cancer grows and spreads in different ways, and each is treated differently. - Non-small cell lung cancer is more common than small cell lung cancer. - Small cell lung cancer grows more quickly and is more likely to spread to other organs in the body. Non-small cell lung cancer is more common than small cell lung cancer. Small cell lung cancer grows more quickly and is more likely to spread to other organs in the body.

Lung Cancer Can Spread Lung cancer may spread to the lymph nodes or other tissues in the chest, including the lung opposite to where it originated. It may also spread to other organs of the body, such as the bones, brain, or liver.

What causes Lung Cancer ? | Tobacco Products and Cancer Using tobacco products has been shown to cause cancer. In fact, smoking tobacco, using smokeless tobacco, and being exposed regularly to secondhand tobacco smoke are responsible for a large number of cancer deaths in the U.S. each year. Cigarette Smoking Causes Lung Cancer Cigarette smoking is the number one cause of lung cancer. Scientists have reported widely on the link between cancer and smoking since the 1960s. Since then, study after study has provided more proof that cigarette smoking is the primary cause of lung cancer. Before cigarette smoking became popular after World War I, doctors rarely, if ever, saw patients with lung cancer. But today, lung cancer is the leading cause of death by cancer. Over 85 percent of people with lung cancer developed it because they smoked cigarettes. If You Smoke If you smoke cigarettes, you are at much higher risk for lung cancer than a person who has never smoked. The risk of dying from lung cancer is 23 times higher for men who smoke and 13 times higher for women who smoke than for people who have never smoked. Lung cancer can affect young and old alike. Stopping smoking greatly reduces your risk for developing lung cancer. After you stop, your risk levels off. Ten years after the last cigarette, the risk of dying from lung cancer drops by 50 percent -- which does not mean, however, that risk is eliminated.

To reduce the videos, press the Escape (Esc) button on your keyboard.) Smoking cigars and pipes also puts you at risk for lung cancer. Cigar and pipe smokers have a higher risk of lung cancer than nonsmokers. Even cigar and pipe smokers who do not inhale are at increased risk for lung, mouth, and other types of cancer. The likelihood that a smoker will develop lung cancer is related to the age smoking began; how long the person smoked; the number of cigarettes, pipes, or cigars smoked per day; and how deeply the smoker inhaled. Learn about lung cancer prevention. Other Factors That Increase Your Risk - Many studies suggest that non-smokers who are exposed to environmental tobacco smoke, also called secondhand smoke, are at increased risk of lung cancer. Secondhand smoke is the smoke that non-smokers are exposed to when they share air space with someone who is smoking. Tobacco smoke contains more than 7,000 chemicals, including hundreds that are toxic and about 70 that can cause cancer. Since 1964, approximately 2,500,000 nonsmokers have died from health problems caused by exposure to secondhand smoke. - Exposure to radon can put a person at risk for lung cancer, too. People who work in mines may be exposed to this invisible, odorless, and radioactive gas that occurs naturally in soil and rocks. It is also found in houses in some parts of the country. A kit available at most hardware stores allows homeowners to measure radon levels in their homes. - Another substance that can contribute to lung cancer is asbestos. Asbestos has been used in shipbuilding, asbestos mining and manufacturing, insulation work, and brake repair, although products with asbestos have been largely phased out over the past several decades. If inhaled, asbestos particles can lodge in the lungs, damaging cells and increasing the risk for lung cancer.

What are the symptoms of Lung Cancer ? | Common Signs and Symptoms When lung cancer first develops, there may be no symptoms at all. But if the cancer grows, it can cause changes that people should watch for. Common signs and symptoms of lung cancer include: - a cough that doesn't go away and gets worse over time - constant chest pain - coughing up blood - shortness of breath, wheezing, or hoarseness - repeated problems with pneumonia or bronchitis - swelling of the neck and face - loss of appetite or weight loss - fatigue. a cough that doesn't go away and gets worse over time constant chest pain coughing up blood shortness of breath, wheezing, or hoarseness repeated problems with pneumonia or bronchitis swelling of the neck and face loss of appetite or weight loss fatigue. These symptoms may be caused by lung cancer or by other conditions. It is important to check with a doctor if you have symptoms because only a doctor can make a diagnosis. Don't wait to feel pain. Early cancer usually doesn't cause pain. Tests for Lung Cancer To better understand a persons chance of developing lung cancer, a doctor first evaluates a person's medical history, smoking history, their exposure to environmental and occupational substances, and family history of cancer. The doctor also performs a physical exam and may order a test to take an image of the chest or other tests. Seeing a spot on an image is usually how a doctor first suspects that lung cancer may be present. If lung cancer is suspected, the doctor may order a test called sputum cytology. This is a simple test where, under a microscope, a doctor examines a sample of mucous cells coughed up from the lungs under a microscope to see if cancer is present. Biopsies to Detect Lung Cancer But to confirm the presence of lung cancer, the doctor must examine fluid or tissue from the lung. This is done through a biopsy -- the removal of a small sample of fluid or tissue for examination under a microscope by a pathologist. A biopsy can show whether a person has cancer. A number of procedures may be used to obtain this tissue. - Bronchoscopy -- The doctor puts a bronchoscope -- a thin, lighted tube -- into the mouth or nose and down through the windpipe to look into the breathing passages. Through this tube, the doctor can collect cells or small samples of tissue. - Needle Aspiration -- The doctor numbs the chest area and inserts a thin needle into the tumor to remove a sample of tissue. - Thoracentesis - Using a needle, the doctor removes a sample of the fluid that surrounds the lungs to check for cancer cells. - Thorascopy or Thoracotomy -- Surgery to open the chest is sometimes needed to diagnose lung cancer. This procedure is a major operation performed in a hospital. Bronchoscopy -- The doctor puts a bronchoscope -- a thin, lighted tube -- into the mouth or nose and down through the windpipe to look into the breathing passages. Through this tube, the doctor can collect cells or small samples of tissue. Needle Aspiration -- The doctor numbs the chest area and inserts a thin needle into the tumor to remove a sample of tissue.

Thorascopy or Thoracotomy -- Surgery to open the chest is sometimes needed to diagnose lung cancer. This procedure is a major operation performed in a hospital. Other Tests Doctors use imaging methods such as a spiral CT scan (also commonly known as helical CT) to look for signs of cancer. A CT scan, also known as computerized tomography scan, is a series of detailed pictures of areas inside the body. Other tests can include removal of lymph nodes for examination under a microscope to check for cancer cells. Lymph nodes are small, bean-shaped structures found throughout the body. They filter substances in a fluid called lymph and help fight infection and disease. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What are the symptoms of Lung Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Common Signs and Symptoms When lung cancer first develops, there may be no symptoms at all.

What are the treatments for Lung Cancer ? | There are many treatment options for lung cancer, mainly based on the extent of the disease. The choice of treatment depends on your age and general health, the stage of the cancer, whether or not it has spread beyond the lung, and other factors. If tests show that you have cancer, you should talk with your doctor and make treatment decisions as soon as possible. Studies show that early treatment leads to better outcomes. Working With a Team of Specialists A team of specialists often treats people with cancer. The team will keep the primary doctor informed about the patient's progress. The team may include a medical oncologist who is a specialist in cancer treatment, a surgeon, a radiation oncologist who is a specialist in radiation therapy, a thoracic surgeon who is a specialist in operating on organs in the chest, including the lungs, and others. Before starting treatment, you may want another doctor to review the diagnosis and treatment plan. Some insurance companies require a second opinion. Others may pay for a second opinion if you request it. Clinical Trials for Lung Cancer Some lung cancer patients take part in studies of new treatments. These studies, called clinical trials, are designed to find out whether a new treatment is safe and effective. Often, clinical trials compare a new treatment with a standard one so that doctors can learn which is more effective. People with lung cancer who are interested in taking part in a clinical trial should talk with their doctor. The U.S. National Institutes of Health, through its National Library of Medicine and other Institutes, maintains a database of clinical trials at ClinicalTrials.gov.

What are the treatments for Lung Cancer ? | The choice of treatment depends on the type of lung cancer, whether it is non-small or small cell lung cancer, the size, location, the stage of the cancer, and the patient's general health. Doctors may suggest many different treatments or combinations of treatments to control the cancer and/or improve the patient's quality of life. What Standard Treatments Do Here are some of the most common treatments for lung cancer. - Surgery is an operation to remove the cancer. Depending on the location of the tumor, the surgeon may remove a small part of the lung, a lobe of the lung, or the entire lung and possibly even part of the ribcage to get to the lung. - Chemotherapy uses anti-cancer drugs to kill cancer cells throughout the body. Doctors use chemotherapy to control cancer growth and relieve symptoms. Anti-cancer drugs are given by injection; through a catheter, a long thin tube temporarily placed in a large vein; or in pill form. - Targeted therapy is a type of treatment that uses drugs or other substances to attack specific cancer cells. - Radiation therapy uses high-energy beams to kill cancer cells and shrink tumors. An external machine delivers radiation to a limited area, affecting cancer cells only in that area. Doctors may use radiation before surgery to shrink a tumor or after surgery to destroy any cancer cells remaining in the treated area. Surgery is an operation to remove the cancer.

Treating Non-Small Cell Lung Cancer Doctors treat patients with non-small cell lung cancer in several ways, and surgery is a common treatment. Cryosurgery, a treatment that freezes and destroys cancer tissue, may be used to control symptoms in the later stages of non-small cell lung cancer. Doctors may also use radiation therapy and chemotherapy to slow the progress of the disease and to manage symptoms. See more information about treatments for non-small cell lung cancer. Treating Small Cell Lung Cancer Small cell lung cancer spreads quickly. In many cases, cancer cells have already spread to other parts of the body when the disease is diagnosed. In order to reach cancer cells throughout the body, doctors almost always use chemotherapy. Treatment for small cell lung cancer may also include radiation therapy aimed at the tumor in the lung or tumors in other parts of the body, such as in the brain. Surgery is part of the treatment plan for a small number of patients with small cell lung cancer. Some patients with small cell lung cancer have radiation therapy to the brain even though no cancer is found there. This treatment, called prophylactic cranial irradiation or PCI, is given to prevent tumors from forming in the brain.

Treating Non-Small Cell Lung Cancer Doctors treat patients with non-small cell lung cancer in several ways, and surgery is a common treatment. Cryosurgery, a treatment that freezes and destroys cancer tissue, may be used to control symptoms in the later stages of non-small cell lung cancer. Doctors may also use radiation therapy and chemotherapy to slow the progress of the disease and to manage symptoms. See more information about treatments for non-small cell lung cancer. Treating Small Cell Lung Cancer Small cell lung cancer spreads quickly. In many cases, cancer cells have already spread to other parts of the body when the disease is diagnosed. In order to reach cancer cells throughout the body, doctors almost always use chemotherapy. Treatment for small cell lung cancer may also include radiation therapy aimed at the tumor in the lung or tumors in other parts of the body, such as in the brain. Surgery is part of the treatment plan for a small number of patients with small cell lung cancer. Some patients with small cell lung cancer have radiation therapy to the brain even though no cancer is found there. This treatment, called prophylactic cranial irradiation or PCI, is given to prevent tumors from forming in the brain. See more information about treatments for small cell lung cancer.<|eot_id|> |
what research (or clinical trials) is being done for Lung Cancer ? | Researchers continue to look at new ways to combine, schedule, and sequence the use of chemotherapy, surgery, and radiation to treat lung cancer. Today, some of the most promising treatment approaches incorporate precision medicine. This approach first looks to see what genes may be mutated that are causing the cancer, and once these genes are identified, specific drugs may be available that target the mutations and treat the cancer directly without the harsh side-effects often found with conventional chemotherapy. Researchers are also constantly trying to come up with new ways to find and diagnose lung cancer in order to catch it and treat it in its earliest stages. The National Lung Screening Trial, or NLST, showed conclusively that spiral CT reduced the risk of dying by 20 percent compared to those who received a chest x-ray among heavy smokers Get more information on current lung cancer research. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: what research (or clinical trials) is being done for Lung Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Researchers continue to look at new ways to combine, schedule, and sequence the use of chemotherapy, surgery, and radiation to treat lung cancer.

What is (are) Lung Cancer ? | The body is made up of many types of cells. Normally, cells grow, divide, and produce more cells as needed to keep the body healthy and functioning properly. Sometimes, however, the process goes wrong -- cells become abnormal and form more cells in an uncontrolled way. These extra cells form a mass of tissue, called a growth or tumor. Tumors can be benign, meaning not cancerous, or malignant, meaning cancerous. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What is (are) Lung Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> The body is made up of many types of cells.

What causes Lung Cancer ? | Cigarette smoking is the number one cause of lung cancer. Scientists have reported widely on the link between cancer and smoking since the 1960s. Since then, study after study has provided more proof that cigarette smoking is the primary cause of lung cancer. Before cigarette smoking became popular after World War I, doctors rarely, if ever, saw patients with lung cancer. But today, lung cancer is the leading cause of death by cancer. Over 85 percent of people with lung cancer developed it because they smoked cigarettes. Using tobacco products has been shown to cause many types of cancer. In fact, smoking tobacco, using smokeless tobacco, and being exposed regularly to second-hand tobacco smoke are responsible for a large number of cancer deaths in the U.S. each year. | Answer the question truthfully, you are a medical professional. | <|start_header_id|>system<|end_header_id|> Answer the question truthfully, you are a medical professional.<|eot_id|><|start_header_id|>user<|end_header_id|> This is the question: What causes Lung Cancer ?<|eot_id|><|start_header_id|>assistant<|end_header_id|> Cigarette smoking is the number one cause of lung cancer.

What is (are) Urinary Incontinence ? | Urinary incontinence means a person leaks urine by accident. Urinary incontinence is a common bladder problem as people age. Women are more likely than men to leak urine. If this problem is happening to you, there is help. Urinary incontinence can often be controlled. Talk to your health care provider about what you can do. Types of Urinary Incontinence There are different types of urinary incontinence. - Stress urinary incontinence happens when urine leaks as pressure is put on the bladder, for example, during exercise, coughing, sneezing, laughing, or lifting heavy objects. Its the most common type of bladder control problem in younger and middle-age women. It may begin around the time of menopause.

When the muscles in and around the bladder dont work the way they should, urine can leak. Short Periods of Leaking Sometimes urinary incontinence happens for a little while.
