A blood screening test for ovarian cancer could catch the disease at the earliest stage.

Ovarian cancer is often deadly because it is has few, if any, symptoms and there is no screening test.

Researchers at MD Anderson Cancer Center in Houston had 4,000 post-menopausal women undergo a blood test that looks for CA-125, a known ovarian tumor marker.

Researchers found the test had a low false positive rate and of the seven women whose cancers were diagnosed as a result of the test all of their cancers were detected at an early stage.
