Some types of breast cancer are affected by hormones in the blood. ER-positive and PR-positive breast cancer cells have receptors proteins that attach to estrogen, which helps them grow. There are different ways to stop estrogen from attaching to these receptors. Hormone therapy is a form of systemic therapy, meaning it reaches cancer cells almost anywhere in the body and not just in the breast. Hormone therapy is often used after surgery as adjuvant therapy to help reduce the risk of the cancer coming back. Sometimes it is started before surgery as neoadjuvant therapy as well.
