The CA 125 Test measures the concentration of cancer antigen 125 in the blood, a protein commonly elevated in ovarian cancer patients. It is used primarily to monitor ovarian cancer treatment progress or detect recurrence after therapy. The test is performed through a simple blood draw and is often paired with imaging studies for a comprehensive evaluation. Although CA 125 can also be elevated due to benign conditions such as endometriosis, menstruation, or pelvic inflammatory disease, persistent elevation should prompt further investigation. Women experiencing symptoms like abdominal bloating, pelvic pain, or unexplained weight loss, especially those with a family history of ovarian or breast cancer, benefit from this test. Regular monitoring through the CA 125 test aids oncologists in adjusting treatment plans and assessing disease response, making it a valuable tool for effective ovarian cancer management and follow-up care.
