Chemotherapy is a form of cancer treatment that uses chemical drugs to target and eliminate fast-growing cancer cells in the body. Unlike surgery and radiation therapy that focus on a specific area, chemotherapy can affect the entire body. It may be used alone or in combination with other treatments. Although chemotherapy can be used to treat non-cancerous conditions, the doses used are typically lower and the side effects are minimized. The primary goals of chemotherapy are to cure cancer, control its growth, and alleviate symptoms associated with the disease.
