Best Practices for Hormonal Contraception and Menopause Therapy in Women at Increased Risk for Breast Cancer

AbstractPurpose of ReviewThe present review critically assesses contemporary evidence characterizing the association between hormonal contraception (HC) and/or menopausal hormone replacement therapy (MHT) and breast cancer risk in patients considered “high risk.”Recent FindingsProspective studies of hormonal contraception methods for BRCA 1 mutation carriers do not demonstrate an association between combined oral contraceptives (COC) and hormone receptor-positive breast cancer, findings consistent with those seen from systematic reviews evaluating this risk in patients with a family history of breast cancer. The Centers for Disease Control and Prevention (CDC) assigns progesterone-only and combined contraception a medical eligibility criteria (MEC) rating of 1, denoting no restrictions on use for those with benign breast disease and a family history of breast cancer. These guidelines include the etonogestrel implant, injected medroxyprogesterone acetate, levonorgestrel intrauterine device, combined oral contraceptive pill, patch, and intravaginal ring, and the recommendation highlights their overall safety in this population. However, the intravaginal ring, which contains the lowest systemic dose of ethinyl estradiol, as well as the locally-acting progestin intrauterine device systems can be considered for those concerned about hormonal exposure. The small potential breast cancer risk increase observed with progesterone-based birth control methods in few studies should be...
