What conditions other than ovarian cancer can cause an elevated CA-125?
Fredric V. Price, MD (Febuary 6, 2006): Unfortunately, the CA-125 test will become elevated for a variety of reasons that have nothing to do with ovarian cancer. The most common reasons for CA-125 elevation in a random sample of the population include endometriosis, fibroids of the uterus, diverticulosis, and cirrhosis. Because these conditions often cause abdominal crampy pain and bloating, confirming a clinical suspicion of ovarian cancer cannot be done with a CA-125 blood test.
