Brachytherapy is a minimally invasive procedure that involves the use of radioactive seeds the size of rice grains. Brachytherapy, an out-patient procedure, usually takes 45 minutes to an hour to perform. Most patients can return to their normal activities within days. The success rates of prostate brachytherapy have compared favorably with success rates of radical prostatectomy and external beam radiation. In comparison studies, prostate brachytherapy has shown to have a favorable side effect profile when compared with other modalities. Clinical studies have shown that prostate brachytherapy has a cure rate of 94% for appropriately selected patients.
