Watch Douglas W. Widman, M.D., Medical Director at Columbus CyberKnife, and Thomas, a CyberKnife patient, talk about how CyberKnife is an excellent treatment option for prostate cancer. CyberKnife is as effective as surgery and is completed in only 5 outpatient treatment sessions compared to the 44 you have with traditional radiation therapy. In addition, CyberKnife treatment is painless, there are minimal (if any) side effects, and there is no disruption to your daily life.
