Breast Cancer Risk and Ovariectomy, Hysterectomy, and Tubal Sterilization

Removal or impairment of ovaries before menopause may affect a woman’s breast cancer risk by altering her cumulative exposure to ovarian hormones.The Women’s Contraceptive and Reproductive Experiences Study, a population-based, multicenter case-control study of incident invasive breast cancer, recruited women aged 35–64 years (4,490 cases and 4,611 controls) who provided data on ovariectomy, hysterectomy, and tubal sterilization during in-person interviews. Controls were frequency-matched to cases by age, race, and study site.

Unconditional logistic regression analysis was used. Women who had not undergone premenopausal reproductive surgery were the referent group. Bilateral ovariectomy was associated with reduced breast cancer risk overall.
