Chemotherapy:
Chemotherapy uses anticancer medications that are either given intravenously or taken by mouth (orally). These drugs enter the bloodstream and travel to all parts of the body, killing cancer cells that have spread to different organs. Chemotherapy is used as the primary treatment for cancers that have spread beyond the lung and cannot be removed by surgery. It also can be used in addition to surgery or radiation therapy to kill any remaining cancer cells.
Chemotherapy is tailored to each patient's needs. Most patients are given a combination of several different drugs. Besides killing the cancer cells, these drugs also harm normal cells. Hence, the dose has to be carefully adjusted to minimize damage to normal cells.
