Bile duct cancer
Definition of Cholangiocarcinoma
Cholangiocarcinoma is a cancerous (malignant) growth in one of the ducts that carries bile from the liver to the small intestine.
Causes, incidence, and risk factors
Cancerous of the bile ducts are usually slow-growing and do not spread (metastasize) quickly. However, many of these tumors are already advanced by the time they are found.
Signs and tests
Your health care provider will perform a physical exam. Tests will be done to check for a tumor or blockage in the bile duct. These may include:
The goal is to treat the and the blockage it causes. When possible, surgery to remove the tumor is the treatment of choice and may result in a cure. If the tumor is large, the entire liver may need to be removed and a liver transplant will be needed. However, often the cancer has already spread by the time it is diagnosed.
Completely removing the tumor allows 30 – 40% of patients to survive for at least 5 years, with the possibility of a complete cure.
