There's a blood test to detect ovarian cancer that is similar in accuracy to a PSA test for prostate screening. The test is called a CA-125 blood test. The only problem is your doctor may not know about it and your insurance company may not know about it either. To get it covered you may have to do some education of your doctor and insurance company.
The normal range on the test is between zero and 35. If the number is slightly above 35, then have another test done in three to six months. Since there is no age factor for ovarian cancer, have the test done every year.
