What is CA 125?

CA 125 is a blood test used to check for the presence of the protein CA 125 (cancer antigen 125), which may be elevated in people with ovarian cancer. The test is not recommended for those with an average risk of ovarian cancer, but it can be used to help monitor how well treatment is working and if the cancer has returned after treatment. The CA 125 test can also detect other cancers, such as endometrial, pancreatic, and colorectal cancers. It's important to speak to your doctor about any potential risks or concerns before having this test.
