The short answer
Bile duct cancer often first shows up as jaundice (yellowing of the skin and eyes), itching, pale stools, and dark urine, caused by a blocked bile duct. Abdominal pain and weight loss can also occur. New jaundice with fever and chills can mean the duct is infected, called cholangitis, which is a medical emergency.
Jaundice — yellowing of the skin and whites of the eyes — is often the first sign of bile duct cancer, caused by a blocked bile duct.
Other symptoms linked to a blocked duct include itching, pale or clay-colored stools, and dark urine.
Abdominal pain, loss of appetite, and unexplained weight loss can also occur, though early bile duct cancer often causes little or no pain.
New jaundice along with fever and chills can mean the bile duct is blocked and infected — a condition called cholangitis — which is a medical emergency.

The full explanation.
The simple version
Bile duct cancer, also called cholangiocarcinoma, often first shows up because a tumor blocks the flow of bile — a digestive fluid made in the liver that normally flows through thin tubes (bile ducts) into the intestine. When bile backs up, it causes a recognizable set of symptoms.
Symptoms
- Jaundice — yellowing of the skin and the whites of the eyes, usually the first sign people notice
- Itching, from bilirubin building up in the skin
- Pale, clay-colored, or greasy stools
- Dark urine
- Abdominal pain, usually below the right ribs, though early bile duct cancer often causes little or no pain
- Loss of appetite and unexplained weight loss
- Fever, in some cases
When jaundice is a medical emergency
If jaundice appears together with fever and chills (shaking), it can mean the blocked bile duct has become infected — a condition called cholangitis. This is a medical emergency. Without prompt treatment, the infection can spread into the bloodstream and become life-threatening.
If you or someone you're with has yellowing skin or eyes along with fever and chills, seek emergency care right away — go to the nearest emergency department.
Why jaundice always needs a prompt medical check
Jaundice is far more often caused by something other than cancer — gallstones blocking a duct, hepatitis, or other liver conditions are all more common. But because the cause of jaundice can't be told just by how it looks or feels, any new jaundice needs a prompt medical evaluation, usually starting with blood tests and imaging of the liver and bile ducts.

Common questions
What is the most common early sign of bile duct cancer?
Jaundice — yellowing of the skin and the whites of the eyes — is often the first noticeable sign. It happens when a tumor blocks a bile duct, causing a substance called bilirubin to build up in the blood.
What other symptoms go along with jaundice?
Itching, caused by bilirubin building up in the skin; pale, clay-colored, or greasy stools; and dark urine. These all relate to bile flow being blocked and are common together.
Does bile duct cancer cause pain?
Not usually in its early stages. Pain, typically below the right ribs, tends to appear later, along with loss of appetite and unexplained weight loss.
When is jaundice a medical emergency?
If jaundice appears along with fever and chills (shaking), it can mean the blocked bile duct has become infected — a condition called cholangitis. This is a medical emergency: without prompt treatment, the infection can spread through the bloodstream and become life-threatening. Seek emergency care right away if this combination occurs.
Does jaundice always mean cancer?
No. Jaundice is far more often caused by other conditions, such as gallstones blocking a duct, hepatitis, or other liver problems. Bile duct cancer is rare. Still, any new jaundice needs prompt medical evaluation to find the cause and start the right treatment.

How this page was created
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes. We do not employ clinicians and do not intend to — our work is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source verified. This page was created with AI assistance and checked against the sources listed on it. Source checking is not a medical review.
High-risk topic — talk to your care team. This topic can involve urgent, individual medical decisions. This page is general education only: it cannot tell you whether your situation is an emergency or what you personally should do. Follow your oncology team's instructions and contact them for individual guidance.
Human medical review: not completed. Cancer Explained is not clinician-reviewed, and that is a deliberate design choice rather than a gap we are waiting to close. We restate published federal guidance and cite it; the authority belongs to the source, not to us. That is why every page names where its claims come from — so you can verify us instead of trusting us. Use it to understand your situation and to ask better questions of the people treating you.
