The CyberKnife® robotic radiosurgery system is a widely used form of nonsurgical prostate stereotactic body radiation therapy (SBRT). The American Society for Radiation Oncology (ASTRO) believes that enough clinical evidence exists so that SBRT should be considered an appropriate treatment option for select patients with low- to intermediate-risk prostate cancer. CyberKnife is designed to avoid healthy tissue and critical anatomy, therefore reducing side effects such as erectile dysfunction, urinary and bowel complications.
