Carcinoembryonic Antigen (CEA) Test: Detecting and Monitoring Various Types of Cancer
The Carcinoembryonic Antigen (CEA) test measures the level of CEA in the blood. CEA is a protein that is a type of “tumor marker.” Tumor markers are substances that are often made by cancer cells or by normal cells in response to cancer
- High levels of CEA are normal in healthy, unborn babies, but in adults, abnormal levels of CEA may be a sign of cancer.
Cancers that may cause high levels of CEA include cancers of the:
- Colorectal
- Bladder
- Breast
- Lung
- Ovarian
- Thyroid
Why a CEA Test is Done
A CEA test may be done:
- If the doctor suspects there may be cancer.
- To find out if cancer treatment is working.
- To find out if cancer has come back (recurred) after treatment
How the Test is Done
A sample of blood is taken by inserting a needle into a vein in your arm. No special preparation is needed for this test. If you smoke, you may need to stop for a while before your test. That’s because smoking increases CEA levels
What the Results Mean
High levels of CEA are often found in people who have cancer, but it is essential to note that CEA tests are not used to screen for or diagnose cancer. Many other health problems that aren’t cancer can also cause high CEA levels
. CEA tests are typically used for monitoring response to treatment, including relapses and to look for possible recurrences
. It is also used along with other tests as providers diagnose, treat, and follow up on a range of cancers
