Chemotherapy is a drugs based therapy to destroy cancer cells.
For women with early breast cancer, treatment with chemotherapy can lower the risk of breast cancer coming back or spreading to other parts of the body. Chemotherapy can also increase the chance of surviving breast cancer.
The aim of chemotherapy for metastatic breast cancer is to stop the cancer from growing or spreading, to relieve symptoms and improve quality of life. For some people, chemotherapy can make the cancer smaller. The benefits of treatment with chemotherapy can last for some time – sometimes for years.
