Screening for bile duct cancer

What is cancer screening?

Screening means testing people for early stages of a disease. This is before they have any symptoms. For screening to be useful the tests:

• need to be reliable at picking up cancers

• overall must do more good than harm to people taking part

• must be something that people are willing to do

Screening tests are not perfect and have some risks. The screening programme should also be good value for money for the NHS.

Why isn’t there a screening programme for bile duct cancer in the UK?

There is no screening programme for bile duct cancer in the UK at the moment because:

• doctors wouldn't find many cancers because it's so rare in the UK

• there is no suitable test to use for bile duct cancer screening

• current tests have risks that outweigh the benefits for most people

• the cost of screening would be high

With rare cancers, it is more cost effective to screen people who are thought to be at a higher risk. Talk to your GP if you think you are at a higher than average risk of bile duct cancer. If your doctor agrees that you are at a higher risk, they may be able to give you regular check ups.

Screening for people with primary sclerosing cholangitis (PSC)

Primary sclerosing cholangitis (PSC) is a rare disease that causes inflammation of the bile ducts. People with PSC have an increased risk of developing bile duct cancer. 

You have regular check ups and tests if you are diagnosed with PSC. Doctors can use these tests to look for signs of bile duct cancer.

Research into screening for bile duct cancer

Researchers are currently looking to see if a test called the Galleri blood test can detect some cancers. This is a test for people who don’t have symptoms. One of the cancers they are looking at is bile duct cancer. They hope this test can be used to screen for cancer in the future.
