Summary:
Radiation therapy has long been a tool in the ongoing battle against cancer. But the therapy can harm healthy tissue that surrounds tumors. Now, medical physicists have found a method for delivering radiation that allows physicians to hit tumors without hurting surrounding tissue.

CHICAGO, IL (July 19, 2000)-- Radiation therapy - the treatment of disease with penetrating beams of particles such as x-rays - has long been a primary weapon in the war on cancer. That's because x-rays and other forms of radiation can readily destroy tumors by depositing energy on them. But radiation can also harm healthy tissue, for the very same reason. At an international conference in Chicago next week, medical physicists will discuss what many see as a significant advance in radiation therapy. Known as intensity modulated radiotherapy (IMRT), the new technique enables physicians to deliver greater amounts of radiation to the precise location of a tumor while minimizing the dose to the healthy tissue that surrounds it. Researchers are hopeful that IMRT will improve treatment of many cancers.
