Radiation Therapy
Radiation therapy may be used to treat cancer in almost every part of the body. Sometimes it is used to shrink tumors prior to surgery. Often it is used to prevent the growth of cancer cells that may remain after surgery. In some cases, doctors prefer to use radiation and anticancer drugs, rather than surgery, to destroy the cancer and prevent its recurrence.
As with many other medical treatments, however, there is an element of risk associated with RT. Although extraordinary precautions are taken, there is always the chance that some healthy cells may be destroyed during treatment. However, the benefits derived from killing the cancer cells usually outweigh this risk.
Radiation therapy has the potential to cure certain cancers. It can also prolong a patients life by slowing the growth of certain types of cancer cells. In cases where it is not possible to cure the cancer, RT can even provide relief from pain, bleeding, pressure or other symptoms related to the malignancy. |
