How accurate is CA-125 blood test for ovarian cancer?

CA-125 is a protein found in the blood that can help monitor an ovarian cancer patient's response to treatment. However, it is not a good tool for finding the disease early.

While mammograms can help find early breast cancer and colonoscopies can help prevent colon cancer, there is currently no reliable way to detect ovarian cancer (but researchers at Roswell Park Comprehensive Cancer Center are working hard to change that).

Is there a normal range for CA-125? What does it mean to have elevated CA-125? Peter Frederick, MD, FACOG, Associate Professor of Oncology and Clinical Chief of Gynecology at Roswell Park, sat down to answers some frequently asked questions about this blood test and how it's used to monitor ovarian cancer.
