Key Statistics

• About 8,000 people in the United States develop cholangiocarcinoma each year.
• Cholangiocarcinoma is much more common in Asia and the Middle East, mostly because of a common parasitic infection of the bile duct.
• Almost 2 out of 3 people with cholangiocarcinoma are 65 or older when it is found.
  • The average age of people diagnosed with cancer of the intrahepatic bile ducts is 70.
  • The average age of people diagnosed with cancer of the extrahepatic bile ducts (perihilar or distal cholangiocarcinoma) is 72.
• The chances of survival for patients with bile duct cancer depends to a large extent on its location and how advanced it is when it is found.
