  • A primary or metastatic malignant tumor involving the pancreas. Representative examples include carcinoma and lymphoma.
  • Pancreatic cancer arises when there is uncontrolled growth of the cells that make up the pancreas, a glandular organ behind the stomach. These cancer cells have the ability to invade or spread to other parts of the body. There are a number of types of pancreatic cancer. Pancreatic adenocarcinoma is the most common, accounting for about 85% of cases, and the term "pancreatic cancer" is often used to refer only to that type. Adenocarcinomas start within the pancreatic glands which make digestive enzymes. Several other types of cancer, which collectively represent the majority of the non-adenocarcinomas, can also arise from these cells. One to two in every hundred cases of pancreatic cancer are neuroendocrine tumors, which arise from the hormone-producing neuroendocrine cells of the pancreas. Overall these are generally less aggressive than pancreatic adenocarcinoma. Signs and symptoms of 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.
