Isoray - Innovative Brachytherapy

More doctors have switched to Cesium Blu in the last 12 months than ever before.

Not all brachytherapy radioisotopes are the same. Cesium Blu, Cs-131, offers you a powerful option for treating prostate and other cancers throughout the body. 

Modern brachytherapy starts here.

With higher energy and a shorter half-life than competitors, Cesium Blu is proven to be a highly customized and effective treatment for the rapid recovery of patients in the fight against prostate cancer.
