Breast cancer is a tumor that starts in the cells of the breast, usually developing in the milk producing glands. Some potential causes of breast cancer include being female, increasing age, family history, and lifestyle factors like smoking. Breast cancer can be treated through surgery to remove the tumor, radiation therapy to destroy remaining cancer cells, and chemotherapy which uses medication to destroy cancer cells throughout the body. While breast cancer cannot always be prevented, early detection through screening and treatment can help reduce the risk of the disease spreading.
