How is hormone therapy used to treat breast cancer?
Hormone therapy for HR-positive breast cancer may be given after surgery (also called adjuvant therapy) or before surgery (also called neoadjuvant therapy).
Hormone therapy can also be given if your disease is HR-positive but cannot be treated with surgery, if you’ve had a recurrence, or if you have advanced or metastatic HR-positive breast cancer, meaning it has spread beyond the breast or to distant parts of the body.
