Malignant neoplasm in the parenchyma of the pancreas, often symptomless unless or until the common bile duct is obstructed, whereupon severe progressive jaundice occurs. It may be an extremely painful cancer. The prognosis is always poor, and fatal outcome is common within months of diagnosis. There is often a history of cigarette smoking, and in many cases this appears to be a tobacco-related cancer.
