What is chemotherapy?

Chemotherapy is a medical treatment that involves the use of drugs to kill cancer cells. It is a systemic treatment, which means that it travels throughout the body to reach and attack cancer cells wherever they may be located. Chemotherapy can be used to treat various types of cancer, such as leukemia, lymphoma, breast cancer, lung cancer, and colon cancer. Chemotherapy can be given in different ways, including intravenously (through a vein), orally (in pill form), or through injections. The type of chemotherapy and the method of delivery depends on the type of cancer being treated and the patient’s overall health. Chemotherapy may be used alone or in combination with other treatments, such as surgery and radiation therapy, to improve the chances of a successful outcome.
