Chemotherapy treatment uses medicine to weaken and destroy cancer cells in the body, including cells at the original cancer site and any cancer cells that may have spread to another part of the body.
Chemotherapy is used to treat:
- Early-stage invasive breast cancer to get rid of any cancer cells that may be left behind after surgery and to reduce the risk of the cancer coming back.
- Advanced-stage breast cancer to destroy or damage the cancer cells as much as possible. In some cases, chemotherapy is given before surgery to shrink the cancer.
