Together, you and your health care provider make breast cancer treatment decisions. After you get a recommended treatment plan from your provider, take time to study your treatment options and make thoughtful, informed decisions.
The goal of treating early breast cancer is to get rid of the cancer and keep it from coming back.
Breast cancer treatment can be divided into local and systemic therapy.
Local therapy removes the cancer from a limited (local) area, such as the breast, chest wall or lymph nodes in the underarm area. It also helps ensure the cancer doesn’t come back to that area.
Local therapy involves surgery, with or without radiation therapy to the breast area.
The goal of breast cancer surgery is to remove the entire tumor from the breast.
Some of the lymph nodes from the underarm area (axillary nodes) may also be removed to see if cancer cells are present.
There are 2 basic types of breast cancer surgery:
Learn about deciding between lumpectomy and mastectomy.
Learn about breast reconstruction.
The goal of radiation therapy is to kill any cancer cells that might be left in or around the breast after surgery. These cells are too small to see on scans or to be measured with lab tests.
Learn about going through radiation therapy.
Learn about the side effects of radiation therapy.
Learn about emerging areas in radiation therapy.
The goal of systemic therapy is to get rid of cancer cells that may have spread from the breast to other parts of the body. These cells are too small to be seen on scans or to be measured with lab tests.
Systemic therapy uses drug therapies that travel throughout the body to get rid of cancer cells. It includes chemotherapy, hormone therapy and HER2-targeted therapy.
Some drug therapies are given by vein (through an IV) and some are pills.
Because systemic therapy is used in addition to (an adjunct to) breast surgery, these treatments are often called adjuvant therapy.
Chemotherapy drugs kill or disable cancer cells.
For people with early breast cancer, chemotherapy is usually given after breast surgery, but before radiation therapy.
In women with large tumors who need a mastectomy, chemotherapy may be used before surgery (called neoadjuvant chemotherapy). Neoadjuvant chemotherapy may shrink the tumor enough so a lumpectomy becomes an option.
Neoadjuvant chemotherapy may also be given to women who have enlarged lymph nodes in the underarm area (due to breast cancer). Neoadjuvant chemotherapy may shrink the tumors in the lymph nodes and make it easier to remove these nodes during surgery.
Women with locally-advanced or inflammatory breast cancer usually begin treatment with neoadjuvant chemotherapy.

Learn about emerging areas in chemotherapy.
Some breast cancer cells need estrogen and/or progesterone (hormones in the body) to grow. Hormone therapy slows or stops the growth of these tumors by preventing the cancer cells from getting the hormones they need to grow.
Hormone therapy is usually given after surgery.
In some postmenopausal women, hormone therapy may be used before surgery (called neoadjuvant hormone therapy) to try and shrink a tumor enough so a lumpectomy becomes an option to a mastectomy.

Learn about the side effects of ovarian suppression.
Learn about emerging areas in hormone therapy.
Some breast cancers have high amounts of a protein called HER2 on the surface of the cancer cells (called HER2-positive breast cancer). The HER2 protein is an important part of the pathway for cell growth and survival.
HER2-targeted therapies are used to treat HER2-positive breast cancers. Unlike chemotherapy, HER2-targeted therapies only kill HER2-positive cancer cells with little harm to healthy cells.
