More than 22,000 U.S. women are diagnosed with ovarian cancer each year, and more than 15,000 die. Symptoms such as pain and bloating seldom are obvious until the cancer is more advanced. Numerous attempts at screening tests have failed.
Endometrial cancer affects about 47,000 women a year, and kills about 8,000. There is no screening test for it either, but most women are diagnosed early because of postmenopausal bleeding.
