Radiation therapy
is the therapeutic use of high energy x-rays to treat cancerous
tumors or areas from which tumors were removed. Radiation
therapy may be used to try to cure cancer, to control the growth
of the cancer or to relieve symptoms such as pain. Unlike other
forms of x-rays, therapeutic radiation is more penetrating
and focused. The radiation disrupts the genetic make-up of
both normal and cancerous cells. The damage to normal cells
is usually temporary and repairable; however, the damage
to cancer cells is intended to be permanent. This damage helps
to prevent the cancerous cells from reproducing. Sometimes,
radiation therapy is the only treatment a patient needs,
and other times it is integrated with chemotherapy and/or surgery.
Some patients have concerns about the safety of radiation
therapy. Radiation has been used successfully to treat
patients for more than a century. External beam treatments,
such as those provided at this Center, do not cause the
patient to become radioactive following treatment because
the radiation does not stay in the body.
