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 is also called cholangiocarcinoma. It often shows up first because a tumor blocks the flow of bile. Bile is a digestive fluid made in the liver. It normally flows through thin tubes, called bile ducts, into the intestine. When bile backs up, it causes a set of symptoms you can recognize.
Symptoms
- Jaundice — yellowing of the skin and the whites of the eyes. This is usually the first sign people notice.
- Itching, from bilirubin building up in the skin.
- Pale, clay-colored, or greasy stools.
- Dark urine.
- Belly pain, usually below the right ribs. But early bile duct cancer often causes little or no pain.
- Loss of appetite, and weight loss you cannot explain.
- Fever, in some cases.
When jaundice is a medical emergency
Jaundice can show up along with fever and chills (shaking). That may mean the blocked bile duct has become infected. This is called cholangitis, and it is a medical emergency. Without prompt treatment, the infection can spread into the blood and become life-threatening.
If you or someone you are with has yellow 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 check
Jaundice is far more often caused by something other than cancer. Gallstones blocking a duct, hepatitis, and other liver problems are all more common. But you cannot tell the cause just from how jaundice looks or feels. So any new jaundice needs a prompt medical check. That usually starts with blood tests and imaging of the liver and bile ducts.
When to get help sooner
- Call 911 or go to an emergency department if your skin or the whites of your eyes turn yellow and you also have fever or shaking chills. That combination can mean an infected bile duct, called cholangitis, and it is an emergency. Go right away too if you have severe pain below the right ribs, are confused or very drowsy, or feel faint.
- Call your care team the same day if your skin or eyes turn yellow with no fever, your urine turns dark, or your stools turn pale or clay-colored. New jaundice always needs a prompt check, even when you feel otherwise well.
- Call your care team within a day or two if itching is keeping you from sleeping, you have belly pain that keeps coming back, or you are losing weight or appetite without trying.

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 checked. This page was written with AI assistance and checked line by line against the sources listed on it. That confirms the sources support what the page says. It is not a medical review, and it does not confirm the page is complete or right for your situation.
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. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
