IsoRay seeds implanted into human prostate for first time; shares spike

|By:, SA News Editor

IsoRay (ISR) shares jump 12.9% after the company says that its Cesium-131 seeds have been inserted into a human prostate for the first time.

Steven Frank of the Anderson Cancer Center, who performed the implant, said that with its short half-life, Cesium-131 "offers rapid resolution of the acute side effects that can be associated with prostate treatment with brachytherapy".

IsoRay's technology enables doctors to directly place radiation in areas where cancer is most likely to remain after a tumor is removed. (PR)
