Now higher doses of radiation can be delivered to targeted areas in fewer radiation treatment sessions with hypofractionated radiation therapy. This short-course radiation therapy is giving prostate cancer patients new hope for treating tumors that were previously diagnosed as inoperable or untreatable. Through pencil-thin beams of radiation, systems like the CyberKnife® are able to direct radiation to any part of the body from any direction through a robotic arm. Healthy tissues and organs surrounding the cancer cells only receive a small fraction of the high central dose used for the targeted irradiation, which results in fewer side effects when compared to conventional radiation therapy.
