People with bile duct cancer may experience the following symptoms or signs, usually because the tumor is blocking the bile duct. Sometimes, people with bile duct cancer do not show any of these symptoms. Or, these symptoms may be caused by a medical condition that is not cancer.
One common symptom is jaundice, which is a yellowing of the skin and the whites of the eyes. When the bile duct is blocked, the liver cannot excrete bile, and the bile backs up into the bloodstream. (However, the blockage may not be cancer; it can also be caused by a gallstone or scar tissue.) Bile contains bilirubin, which is dark yellow and can cause the skin and whites of the eyes to turn yellow if there are higher levels of it in the bloodstream. A person’s urine may also become a dark color, and bowel movements may become pale.
It is important to note that jaundice is a common symptom for many conditions, so your doctor may need to do several diagnostic tests (see the Diagnosis  section for a complete list) to find the exact cause. Many diseases associated with jaundice are not serious or life threatening, and bile duct cancer is one of the less common causes.
In addition to jaundice, other symptoms of bile duct cancer include the following:
- Itching, caused by a buildup of bile salts and bilirubin in the body that is then deposited in the skin
- Weight loss
- Loss of appetite
- Abdominal pain (Early bile duct cancer usually does not cause pain, but a person may experience pain if the cancer has spread.)
If you are concerned about one or more of the symptoms or signs on this list, please talk with your doctor. Your doctor will ask how long and how often you’ve been experiencing the symptom(s), in addition to other questions. This is to help find out the cause of the problem, called a diagnosis .
If cancer is diagnosed, relieving symptoms remains an important part of cancer care and treatment. This may also be called symptom management, palliative care, or supportive care. Be sure to talk with your health care team about symptoms you experience, including any new symptoms or a change in symptoms.
