| | Proton Beams Battle Cancer |
 | | Proton beams -- produced by particle accelerators called cyclotrons or synchrotrons -- have produced better results than conventional radiation treatment against advanced cancers of the prostate, bone and eye, researchers told the annual meeting of the Radiological Society of North America. |
 | | "In contrast, the photon beams, used in standard radiation therapy, lose their energy as they pass through the body, so that the dose is maximum near the surface and decreases through the entire thickness of the body," he said. |
 | | Proton beam treatment of a type of cancer that attacks the base of the skull was effective for 92% of 180 patients, compared to about half of patients treated with standard radiation therapy, according to doctors at three Massachusetts facilities. |
