Pancreatic Cancer
Of pancreatic tumors, 95% develop from the exocrine portion of the pancreas. Approximately 75% of all pancreatic carcinomas occur within the head or neck of the pancreas, 15-20% occur in the body of the pancreas, and 5-10% occur in the tail. Typically, pancreatic cancer first metastasizes to regional lymph nodes, then to the liver, and less commonly, to the lungs. It can also directly invade surrounding visceral organs such as the duodenum, stomach, and colon. Early diagnosis of pancreatic cancer is difficult because the symptoms are so non-specific and varied. Common symptoms include abdominal pain, loss of appetite, significant weight loss and painless jaundice. Surgical removal ("resection") of the cancer is currently the only chance for a cure for patients with cancer of the pancreas. The surgical resection of most pancreas cancers is called a "pancreaticoduodenectomy" or "Whipple procedure"
