About the Biliary Tract

The biliary tract is made up of a series of thin tubes (bile ducts) that span from the liver to the small intestine. These ducts transport bile to the small intestine where it helps digest the fats in food. The gallbladder, functioning as a reservoir for bile, is connected to the biliary tract. Biliary tract cancer can form anywhere along the biliary tract.

Types of Biliary Tract Cancer

Biliary tract cancer can be categorized into four groups based on where the cancer is located in the biliary tract.

Examples of biliary tract cancer:

  • Intrahepatic cholangiocarcinoma is located in the bile ducts inside the liver.
  • Perihilar (also called hilar) cholangiocarcinoma is located where the left and right hepatic ducts have joined and are just leaving the liver (also known as the hilum of the liver). These are called extrahepatic bile duct cancers since they start outside the liver.
  • Distal cholangiocarcinoma is located further down the bile duct, closer to the small intestine. These are also extrahepatic bile duct cancers.
  • Gallbladder cancer is located in the wall of the gallbladder and grows into the liver.

Symptoms of Biliary Tract Cancer

Biliary tract cancer in any of the four locations described above can cause different symptoms.

Common symptoms of biliary tract cancer include:

  • Yellowing of your skin and the whites of your eyes (jaundice)
  • Intensely itchy skin
  • Clay-colored stools
  • Fatigue
  • Abdominal pain
  • Unintended weight loss

Risk Factors for Biliary Tract Cancer

Women are more likely to be diagnosed with biliary tract cancer than men.

Other risk factors for biliary tract cancer include:

  • Older age, usually over the age of 50, though it can occur at any age
  • History of gall stones
  • Obesity
  • Smoking
  • Parasitic infection of the bile ducts
  • Inflammation of the bile ducts, such as sclerosing cholangitis
