Context: Hormone Therapy for Breast Cancer / How is hormone therapy used to treat breast cancer?

Your doctor may prescribe hormone therapy after surgery (adjuvant therapy) to reduce your risk of new or recurrent breast cancer. Tamoxifen, aromatase inhibitors, and ovarian suppression may all be used as adjuvant therapy.

Men with early-stage ER-positive breast cancer who receive adjuvant therapy are usually treated first with tamoxifen.
