What are the causes of pancreatic cancer?
Pancreatic cancer is a disease in which malignant (cancerous) cells form in the tissues of the pancreas. The pancreas is a gland located behind the stomach and in front of the spine. The pancreasproduces digestive juices and hormones that regulate blood sugar. Cells called exocrine pancreas cells produce the digestive juices, while cells called endocrine pancreas cells produce the hormones. The majority of pancreatic cancers start in the exocrine cells.
Symptoms of pancreatic cancer include:
Symptoms of pancreatic cancer include:
- Jaundice (yellowing of the skin and whites of the eyes)
- Pain in the upper or middle abdomen and back
- Unexplained weight loss
- Loss of appetite
The factors which could put you at risk for developing pancreatic cancer include:
- Chronic pancreatitis (inflammation of the pancreas)
- Inherited conditions (including hereditary pancreatitis)
- Familial pancreatic cancer syndromes
- Long-standing diabetes
Pancreatitis (contrary to apparent belief) is NOT pancreatic cancer. They are entirely different conditions. Pancreatitis literally means "inflammation (or infection) of the p…ancreas". There are MANY causes, though alcohol consumption is one of the leading causes, gallstones are also a common cause of pancreatitis, the two accounting for 80%-90% of all cases. Pancreatitis from alcohol use usually occurs in patients who have been long-term alcohol drinkers for at least five to seven years. Most cases of chronic pancreatitis are due to alcohol abuse. Pancreatitis is often already chronic by the first time the person seeks medical attention (usually for severe pain). Gallstones form from a buildup of material within the gallbladder, another organ in the abdomen (please see previous illustration). A gallstone can block the pancreatic duct, trapping digestive juices inside the pancreas. Pancreatitis due to gallstones tends to occur most often in women older than 50 years of age. The remaining 10%-20% of cases of pancreatitis have various causes, including the following: . medications, . exposure to certain chemicals, . injury (trauma), as might happen in a car accident or bad fall leading to abdominal trauma, . hereditary disease, . surgery and certain medical procedures, . infections such as mumps (not common), . abnormalities of the pancreas or intestine, or . high fat levels in the blood.
Pancreatic Cancer Most pancreatic tumors originate in the duct cells or in the cells that produce digestive enzymes (acinar cells). These tumors account for nearly 95 percen…t of pancreatic cancers. When these cells are healthy, they grow and divide in an orderly way. When DNA is damaged in these cells by certain things, cells may begin to grow out of control and eventually form a tumor. What damages DNA in the majority of cases of pancreatic cancer is unknown, but a small percentage of people develop the disease as a result of a genetic predisposition. These people who have a close relative, such as a parent or sibling, with pancreatic cancer have a higher risk of developing pancreatic cancer themselves. Development of other genetic diseases have been associated with an increased risk of pancreatic cancer, including familial adenomatous polyposis, nonpolyposis colon cancer, familial breast cancer associated with the BRCA2 gene, and hereditary pancreatitis. Only about 10 percent of pancreatic cancers result from an inherited tendency. A greater number are caused by environmental or lifestyle factors, such as smoking, diet and chemical exposure. Smokers are two to three times more likely to develop pancreatic cancer than nonsmokers are. This is probably the greatest known risk factor for pancreatic cancer, with smoking associated with almost one in three cases of pancreatic cancer. A diet high in animal fat and low in fruits and vegetables may increase your risk of pancreatic cancer as well. People who work with petroleum compounds, including gasoline and other chemicals, have a higher incidence of pancreatic cancer than people not exposed to these chemicals on a regular basis. Resent research has also shown that chronic, advanced gum disease seem to be associated with development of pancreatic cancer, but by some unknown mechanism.
Pancreatic Cancer Pancreatic cancer is a tumor or cancerous cells of the pancreas. Symptoms A tumor or cancer in the pancreas may often grow without any symptoms a…t first. This may mean pancreatic cancer is more advanced when it is first found. Early symptoms of pancreatic cancer include: . Pain or discomfort in the upper part of the belly or abdomen . Loss of appetite and weight loss . Jaundice (a yellow color in the skin, mucus membranes, or the eyes) . Dark urine and clay-colored stools . Fatigue and weakness . Nausea and vomiting Other possible symptoms are: . Back pain . Blood clots . Depression . Diarrhea . Difficulty sleeping . Indigestion Treatment Because pancreatic cancer is often advanced when it is first found, very few pancreatic tumors can be removed by surgery. The standard procedure is called a pancreaticoduodenectomy (Whipple procedure). This surgery should be done at centers that perform the procedure frequently. Some studies suggest that surgery is best performed at hospitals that do more than five of these surgeries per year. When the tumor has not spread out of the pancreas but cannot be removed, radiation therapy and chemotherapy together may be recommended. When the tumor has spread (metastasized) to other organs such as the liver, chemotherapy alone is usually used. The standard chemotherapy drug is gemcitabine, but other drugs may be used. Gemcitabine can help approximately 25% of patients. Patients whose tumor cannot be totally removed, but who have a blockage of the tubes that transport bile (biliary obstruction) must have that blockage relieved. There are generally two approaches to this: . Surgery . Placement of a tiny metal tube (biliary stent) during ERCP Management of pain and other symptoms is an important part of treating advanced pancreatic cancer. Hospice can help with pain and symptom management, and provide psychological support for patients and their families during the illness. Causes The pancreas is a large organ that is found behind the stomach. It makes and releases enzymes that help the body absorb foods, especially fats. Hormones called insulin and glucagon are also made in the pancreas. These hormones help your body control blood sugar levels. The exact cause is unknown, but pancreatic cancer is more common in smokers and people who are obese. Pancreatic cancer is slightly more common in women than in men. The risk increases with age. A small number of cases are related to genetic syndromes that are passed down through families. Tests & diagnosis . CT scan of the abdomen . MRI of the abdomen . Endoscopic retrograde cholangiopancreatography (ERCP) . Endoscopic ultrasound . Pancreatic biopsy This disease may also affect the results of the following tests: . Liver function tests . Serum bilirubin . Complete blood count (CBC) Prognosis Some patients with pancreatic cancer that can be surgically removed are cured. However, in more than 80% of patients the tumor has already spread and cannot be completely removed at the time of diagnosis. Chemotherapy and radiation are often given after surgery to increase the cure rate (this is called adjuvant therapy). For pancreatic cancer that cannot be removed completely with surgery, or cancer that has spread beyond the pancreas, a cure is not possible and the average survival is usually less than 1 year. Such patients should consider enrolling in a clinical trial (a medical research study to determine the best treatment). Ninety-five percent of the people diagnosed with this cancer will not be alive 5 years later. Prevention . If you smoke, stop smoking. . Eat a diet high in fruits, vegetables, and whole grains. . Exercise regularly. Complications . Blood clots . Depression . Infections . Liver problems . Pain . Weight loss . a canswer that most men get!
The most common causes for pancreatitis are alcohol abuse and gall stones, which account for 80-90% of all cases. Other causes include trauma (accidents, etc), medications, co…mplications from certain surgeries, high fat count and exposure to certain chemicals.
well the trestifonal coclusion mixes with the illaberrital focus to create a very strong acidic mixture. It then goes through a process in which the acid eats up the inside of… the human body. One it enters your body, you have no defense, the acid tears through your glands.
The biggest single risk factor is smoking. Up to a third of pancreatic cancers may be caused by smoking. Cigarette smoke contains chemicals called nitrosamines which are known… to cause cancer. Beer also contains nitrosamines, although the level of these has been cut as much as possible. There has been some evidence of a link between heavy drinking and cancer of the pancreas. Drinking is certainly linked to pancreatic disease and this is a risk factor for cancer. Exposure to some industrial chemicals such as beta-naphthalene and benzidine have been linked to pancreatic cancer. read more at http://cancerlinks.blogspot.com/ -------inherited mutations

No. It is inflammation of the pancreas.
If it spreads it can shut down your body's systems which will painfully kill you.

At first you may have no symptoms. When the cancer is large enough to cause symptoms it has usually grown outside the pancreas. The symptoms depend on the cancers location w…ithin the pancreas. If it is in the head of the pancreas they symptoms will be weight loss, jaundice, and abdominal pain. Cancer in the body or the tail of the pancreas will cause abdominal pain and weight loss. There will eventually be more digestive system complaints such as abdominal pain bloating, satiety or a feeling of fullness, nausea, diarrhea, pale-colored stools. As it grows and spreads the cancer affects the whole body, with malaise and loss of appetite, elevated blood sugars. Jaundice will occur when the cancer blocks the bile duct. Finally there may be a general itch to the skin.

When ionising radiation interacts with living cells is usually kills these cells. Thus yes, radiation can kill pancreatic cells that are cancerous. However the radiation will …also destroy healthy cells (and destroy the pancreas) so the amount of radiation given has to be low and well targeted. This is difficult to achieve and if any cancerous cells remain alive they will regrow the cancer.
