A carcinoembryonic antigen (CEA) test is used to check how well treatment is working in certain types of cancer, particularly colon cancer ↗.
Carcinoembryonic antigens are substances (usually proteins) that are produced by some types of cancer ↗.
In response to the antigens, the body produces antibodies to help fight them.
A CEA test is often carried out after surgery to check carcinoembryonic antigen levels.
As well as being a useful marker for colon cancer, CEA tests can be used to assess other types of cancer, including:
- rectal cancer ↗
- lung cancer ↗
- breast cancer ↗
- liver cancer ↗
- pancreatic cancer ↗
- stomach cancer ↗
- ovarian cancer ↗
