Overview

Chemotherapy for breast cancer uses drugs to target and destroy breast cancer cells. These drugs are usually injected directly into a vein through a needle or taken by mouth as pills.

Chemotherapy for breast cancer frequently is used in addition to other treatments, such as surgery, radiation or hormone therapy. Chemotherapy can be used to increase the chance of a cure, decrease the risk of the cancer returning, alleviate symptoms from the cancer or help people with cancer live longer with a better quality of life.

If the cancer has recurred or spread, chemotherapy may control the breast cancer to help you live longer. Or it can help ease symptoms the cancer is causing.

Chemotherapy for breast cancer also carries a risk of side effects — some temporary and mild, others more serious or permanent. Your doctor can help you decide whether chemotherapy for breast cancer is a good choice for you.
