With CyberKnife, it is possible to treat cancer that is difficult to reach—without surgery. It is one of the newest and most advanced technologies in the field of radiation therapy.

CyberKnife works with great precision and can be an alternative for common treatment options of the prostate, such as prostatectomy. Even advanced prostate carcinomas that have already metastasizedi.e. have already spread throughout the bodycan potentially be treated. The advantage is that the side effects are reduced, compared to common radiation therapies, because the treatment uses highly focussed radiation beams, which make it possible to spare the surrounding organs. Another advantage over other radiation therapies or surgery is that the treatment is on an outpatient basis and under local anesthesia.

Compared to focal treatments like IRE, CyberKnife therapy may require more than one session. While adverse events are less severe compared to other radiation therapies, some adverse events can still applymainly due to delayed radiation effectsthat do not occur with NanoKnife.
