Intensity Modulated Radiation Therapy by Krisha McCoy, MS
Radiation therapy uses radiation to kill cancer cells and shrink
tumors. Intensity modulated radiation therapy (IMRT) uses
radiation beams of different intensities. The beams deliver
appropriate doses of radiation to the tumor and reduce the dose
to nearby healthy tissue. Reasons for Procedure Radiation
therapy works to destroy or shrink the tumor to eliminate or
prevent the spread of cancer. It can also be used to relieve
symptoms caused by the tumor, such as pain and bleeding.
Compared with conventional radiation therapy, IMRT can safely
deliver greater doses of radiation. The higher dose may also
improve the success of the treatment. Possible Complications TOP
Some normal cells will be damaged with radiation. The goal of
radiation therapy is to kill as many cancer cells as possible,
while limiting damage to healthy cells. IMRT is generally
associated with fewer side effects than conventional radiation
therapy. Side effects vary from person to person
