Is common bile duct dilatation cancer?

Common bile duct dilatation is not necessarily cancer.

Common bile duct dilatation is a pathological change, most of the time due to obstruction of bile flow or bile duct compression. When cancer affects the bile duct or biliary system, bile can not be discharged normally, accumulated in the common bile duct, and then make it dilated. However, it should be noted that in addition to cancer, the above conditions may also be related to cholelithiasis, biliary inflammation, congenital abnormalities and other reasons. Therefore, it is recommended that patients take further examinations in time to clarify the specific reasons so as to facilitate the formulation of treatment plans.
