Definition of Cancer, pancreatic

Cancer, pancreatic: A malignant tumor of the pancreas. Pancreatic cancer has been called a 'silent' disease because early pancreatic cancer usually does not cause symptoms. If the tumor blocks the common bile duct, and bile cannot pass into the digestive system, the skin and whites of the eyes may become yellow (jaundiced), and the urine may become darker as a result of accumulated bile pigment (bilirubin).
