For certain breast cancer patients, specialized tumor tests can be used to determine if they are likely to benefit from chemotherapy
The treatments your doctors recommend will be determined by the type of breast tumor you have. Hormonal therapies are used to treat women whose tumors are hormone sensitive -- ER-positive or PR-positive. These treatments slow or stop cancer's growth by keeping estrogen from getting to the tumor. If you have early-stage hormone sensitive breast cancer, your risk of recurrence may be the same if you have hormone therapy alone instead of having chemotherapy and hormone therapy. This video explains how these tests determine who will benefit from chemotherapy and who should have them.
