This factsheet is for people who have bile duct cancer, or who would like information about it.
Bile duct cancer is rare. Around 600 people in the UK are diagnosed with bile duct cancer each year. It's more common in Chile, Japan and Northern India. Bile duct cancer is most common in people aged between 50 and 70. It's rare in people under 40.
Bile duct cancer is also called cholangiocarcinoma.

Legal notices
Bile is a digestive fluid that helps to break down fatty food. It's made in your liver then passes to the gallbladder via the bile duct where it's stored. Bile then passes from the gallbladder into your small bowel through the common bile duct. Bile has a yellow/green colour as it contains bilirubin, which comes from the breakdown of used red blood cells. If bile isn't removed from your blood it builds up and you become jaundiced (yellow skin).

The location of the bile duct and surrounding structures
A bile duct tumour is a lump created by an abnormal and uncontrolled growth of cells. It can be either malignant (cancerous) or benign.
Cancerous tumours can grow through your bile duct and spread to other parts of your body (through the bloodstream or the lymph system) where they may grow and form secondary tumours. This spread of cancer is called a metastasis.
Benign tumours don't spread to other areas of the body.
Bile duct cancer usually starts in the gland cells of the bile duct and is called adenocarcinoma. Part of the bile duct is found in the liver and part of it is outside the liver. If the bile duct cancer is found inside the liver it's called intra-hepatic bile duct cancer. If it's outside the liver it's called extra-hepatic bile duct cancer. Intra-hepatic bile duct cancer is treated in the same way as liver cancer.
This factsheet will focus on extra-hepatic bile duct cancer.
If you have bile duct cancer, you may have some of the following symptoms:
Although not necessarily a result of bile duct cancer, if you have any of these symptoms you should visit your GP.
The causes of bile duct cancer aren't fully understood at present. However, there are certain factors that make bile duct cancer more likely and these are listed below.
Your doctor will ask you about your symptoms and will examine you. Your GP may give you a blood test and may refer you to a different doctor, such as a specialist in conditions that affect the gallbladder, for further tests including the following.
For more information, see Related topics. The results of the tests will determine your course of treatment.
The treatment for bile duct cancer depends on the type, stage and grade of cancer that you may have. Bile duct cancer is often at an advanced stage when it's diagnosed and it may not be possible to cure the cancer. The following treatments may be used even if a cure isn't possible.
Surgery may be used to remove the bile ducts and possibly some of the surrounding tissue and organs if they are also affected by the cancer. This is the only way to cure the cancer. The bile duct is in an awkward position and it may not be possible to remove all of the cancer. Bypass surgery, which allows the bile to flow from the liver to the small bowel, may be suggested if it isn't possible to remove the tumour.
A stent (a small hollow tube) may be inserted to help the bile drain properly into the digestive system and prevent jaundice. This can be added during an ERCP or PTC. A catheter (a longer tube which drains to the outside of the body) can also be inserted.
This uses radiation to destroy cancer cells but isn't generally suitable for bile duct cancer. It's sometimes given at the same time as chemotherapy. For more information, see Related topics.
Medicines to attack cancer cells are given to some people with certain types of cancer. Chemotherapy medicines may be given if the cancer can't be completely removed or has spread elsewhere in the body. In some patients it can shrink the tumour for a short time. You may be offered this type of treatment as part of a clinical trial. For more information, see Related topics.
A light sensitive medicine is injected into your body via a vein and is taken up by cancer cells. A laser is then passed over the cells to activate the medicine which then kills the cells. It's not yet clear how effective this treatment is.
After treatment for cancer you will have regular check ups with your doctor to detect any evidence of the cancer returning. If the cancer has already spread you may be seen regularly by doctors or specialist nurses to arrange treatments that can deal with any symptoms you might develop.
Being diagnosed with cancer can be distressing for you and your family. Specialist cancer doctors and nurses are experts in providing the care and support you need. There may be support groups where you can meet people who may have similar experiences to you. Ask your doctor for advice.
