Ovarian Cancer, Oral Contraceptives, andBRCAMutations

Abstract
Modan and colleagues (July 26 issue)1 conclude that oral contraceptives do not protect against ovarian cancer in Israeli Jewish women carrying BRCA mutations. We have shown, in two studies of Jewish and non-Jewish women with BRCA mutations, that the use of oral contraceptives was strongly protective against ovarian cancer.2,3 In our recent study, the odds ratio for ovarian cancer among women who had used oral contraceptives was 0.44 (95 percent confidence interval, 0.28 to 0.68).3
