Why do I need a CA-125 blood test?
You may need a CA-125 blood test if you are currently being treated for ovarian cancer. Your health care provider may test you at regular intervals to see if your treatment is working, and after your treatment is finished.
You may also need this test if you have certain risk factors for ovarian cancer. You may be at a higher risk if you:
Have inherited a gene that puts you at higher risk of ovarian cancer. These genes are known as BRCA 1 and BRCA 2.
Have a family member with ovarian cancer.
Previously had cancer in the uterus, breast, or colon.
