Living with Klatskin tumor

A cancer of the bile ducts at the spot where they leave the liver, usually found in adults.

Understanding Klatskin tumor

Klatskin tumor is a type of bile duct cancer (cholangiocarcinoma) that starts where the left and right bile ducts join and leave the liver.

It is the most common type of cholangiocarcinoma, making up more than half of all cases. It is usually found in adults. Symptoms include yellowing of the skin and eyes (jaundice), belly pain, unintended weight loss, and feeling unwell.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Yellow skin and eyes (jaundice)
  • Enlarged liver
  • Blocked bile flow (cholestasis)
  • Swollen lymph nodes
  • Belly pain
  • Unintended weight loss

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include cancer specialists and digestive system specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
