Birth control pills may protect against most serious ovarian cancer: study

For several years, researchers have noted that women who have used oral contraceptives are less likely to develop ovarian cancer. This study took a closer look at that link.

Researchers at Roswell Park Comprehensive Cancer Center in Buffalo, N.Y., and the University of Buffalo compared data on 579 patients who died within 12 months of being diagnosed with ovarian cancer to a control group of nearly 2,300 women without ovarian cancer.
