| Chemotherapy is used to kill cancer cells. It may be used alone or in combination with surgery and/or radiation. Chemotherapy is the only treatment for some types of malignancies such as leukemias and lymphomas. Chemotherapy also plays an important role when tumors have spread to multiple, distant sites in the body (metastatic cancer). Chemotherapy may also be used for palliative treatment of a tumor, which serves to relieve or alleviate pain without curing the cancer. Even when recovery is unlikely, an individual's comfort level can be significantly improved if the tumor or cancer is treated and the size reduced. |
