New Study Says Proton Beam Radiation Lowers Cancer Recurrence

American scientists presented a paper saying that proton therapy lowers the risk of developing a second malignancy in cancer patients. The study was released at the American Society for Therapeutic Radiology and Oncology (ASTRO) 50th annual meeting in Boston on September 23, 2008. The new study indicates that new cancers are less likely to occur after proton beam therapy. Compared to the standard x-ray radiation treatment, proton therapy halves the risk of a second cancer. Scientists are optimistic that protons will increase the survival rate of cancer patients. By focusing radiation on the tumoral tissue, protons reduces the impact on the normal tissue and lowers the risk of late-occuring radiation-induced malignances.
