What is the CA 125 test, and how is it used to detect ovarian cancer? - #14732
I recently heard about the CA 125 test, but I don’t fully understand what it measures or how it helps in diagnosing ovarian cancer. I know it’s a blood test, but what exactly does it tell doctors about a person’s health? What is the CA 125 test, and how is it used to detect ovarian cancer? I read that it measures a protein that’s often elevated in ovarian cancer—does that mean every woman with elevated CA 125 levels has cancer, or could it also indicate other conditions like fibroids or endometriosis? I also want to know if the CA 125 test is used for regular screening in healthy women, or is it only recommended when symptoms are present? How accurate is it in detecting early-stage ovarian cancer, and are there any risks associated with false positives or negatives? If anyone has had the CA 125 test, what was it used for, and did it help with diagnosis? Were additional tests necessary to confirm the results?
