Chemotherapy is the use of a type of strong cytotoxic (toxic to cells) medicine to destroy or slow the growth of cancer cells. Chemotherapy works by specifically targeting fast-growing cells, which includes most cancer cells. Most chemotherapy is systemic, i.e. administered into the bloodstream, but in some cases, it’s delivered directly to the cancer site (local chemotherapy). Chemotherapy might be combined with, or used before or after, other cancer treatments including surgery, radiation therapy, hormone therapy, targeted therapy and immunotherapy.
