Findings from the European Prospective Investigation into Cancer and Nutrition, which included some 126,920 post-menopausal women, were presented at a conference of the American Association for Cancer Research this week in Philadelphia.
After nine years of follow-up, 424 ovarian cancers had been diagnosed. Even after controlling for body mass index, smoking, and several other risk factors, researchers found that women taking post-menopausal hormone therapy had a 29 percent greater risk of ovarian cancer, compared with women who did not use hormones.
