Bile duct cancer is also called cholangiocarcinoma. It is a rare type of cancer that starts in the bile ducts.
The bile ducts are small tubes that connect the liver and gallbladder to the small bowel. They carry a fluid called bile. This helps to break down fat from the food we eat making it easier to digest.
