Ovarian Cancer Risk

CA-125 (for females)

CA125 (Cancer Antigen 125) is a protein found in your blood. Women with ovarian cancer may have high levels of CA125, although it’s important to remember some women with ovarian cancer do not have raised CA125 levels (false negative result), and many noncancerous conditions, such as uterine fibroids, can also increase your CA125 levels (false positive result). This test is only recommended for women aged 40-79 due to the risk of false positive or negative results.
