Pancreatic cancer arises when cells in the pancreas, a glandular organ behind the stomach, begin to multiply out of control and form a mass. There are usually no symptoms in the cancer's early stages; by the time of diagnosis, it has often spread to other parts of the body. Symptoms of pancreatic adenocarcinoma, the most common form of pancreatic cancer, may include yellow skin, abdominal or back pain, unexplained weight loss, light-colored stools, dark urine and loss of appetite. It rarely occurs before the age of 40, and more than half of cases occur in those over 70. The risk is lower among non-smokers and people who maintain a healthy weight and limit their consumption of red or processed meat. It can be treated with surgery, radiotherapy, chemotherapy, palliative care, or a combination of these, depending in part on the cancer stage. It is never cured by nonsurgical treatments, though any of these will sometimes improve quality of life, particularly palliative care. It typically has a very poor prognosis: 25% of people live for one year after diagnosis, and 5% for five years. (Full article...)
