Ovarian cancer, the most lethal gynecological cancer known as the "silent killer" because it usually grows undetected until it's too widespread to treat, may not be so invisible after all. Two controversial, early screening techniques may pick up the tumors better than critics previously believed.
A randomized controlled trial of more than 202,000 postmenopausal women found that a blood test to measure a tumor marker called CA-125, followed by a vaginal ultrasound, detected 48 percent of cancers in their early stages, according to a study set to be published in next month’s The Lancet Oncology. Some 90 percent of ovarian cancers are curable when they're caught early, but right now, only a quarter of women are diagnosed at that stage.
