Chemotherapy encompasses a group of drugs which have anti-cancer properties.
Chemotherapy works by interfering with the ability of cells to function and divide, usually by affecting DNA synthesis or function. It may be injected or infused into the blood stream or taken as tablets. Cancer cells are susceptible to different types of chemotherapy drugs at different phases of their cell cycle. Moreover, specific cancers may have individual susceptibility. Furthermore, different drugs may work on different parts of the cancer cell.
