Radiation Therapy News and Research

RSS

Radiation therapy (also called radiotherapy, x-ray therapy, or irradiation) is the use of a certain type of energy (called ionizing radiation) to kill cancer cells and shrink tumors. Radiation therapy injures or destroys cells in the area being treated (the “target tissue”) by damaging their genetic material, making it impossible for these cells to continue to grow and divide. Although radiation damages both cancer cells and normal cells, most normal cells can recover from the effects of radiation and function properly. The goal of radiation therapy is to damage as many cancer cells as possible, while limiting harm to nearby healthy tissue.

Cost-effectiveness of lipid screening in Hodgkin's disease survivors

Hodgkin's lymphoma survivors who have lipid screening every five years to detect high cholesterol will live a half year longer than patients who don't have the screening and the intervention is cost-effective, according to a study presented November 8, 2006, at the American Society for Therapeutic Radiology and Oncology's 48th Annual Meeting in Philadelphia.

Shaped-beam radiosurgery treats tiniest lung tumors

Patients with metastatic cancer tumors in their lungs are much more likely to live disease-free if they have an experimental treatment involving shaped-beam radiosurgery rather that conventional treatment, according to a University of Rochester Medical Center study.
