The ampulla of Vater is the site where the pancreatic duct and bile duct join and drain into the small intestine. Cancer generally starts from the DNA mutation of the normal cells. The mutation of cell causes uncontrolled duplication resulting in a formation of a mass of cells also known as a tumor. This tumor then begins to invade and destroy the healthy tissues. Ampullary cancer is a rare form of cancer and its cause is unknown. It can affect other nearby organs in the digestive system, including liver, pancreas and small intestine.
Signs and symptoms
The following are the signs and symptoms of ampullary cancer:
