How reliable is the ca125 test for ovarian cancer?
4 doctors weighed in across 2 answers
Not very.: Ca 125 is touted as a screening tool for ov ca but is elevated in only 50% of those with early stage disease. Approx 1% of normals have a high ca 125. Since ovarian cancer is relatively uncommon, the ability of a positive test to predict ca is about 3%. There is general consensus that ca 125 is not a good screening tool for average risk females. Consider ca 125 for those with high risk.

CA 125: Ca 125 is not a reliable test to look for ovarian cancer. It is used in follow up of a woman with ovarian cancer or similar cancers.

Ca125 test 7 months ago, raised at 54, repeat test raised at 95, pelvic ultrasound clear. Repeat ca125 back down to 52. Hysteroscopy - benign polyp, removed. If this rise in ca125 was caused by ovarian cancer, would I have symptoms after 7 months?
