In general, there are three methods to treat prostate cancer: brachytherapy (implantation of radioactive seed), external beam radiation therapy (EBRT), and radical prostatectomy surgery (surgical removal of the prostate).
CyberKnife belongs to the second, EBRT. In other words, CyberKnife is a robotic device that helps treat prostate cancer via radiation therapy.
It is different from others in that it checks and compensates for every movement of the prostate. Besides, there is real time patient monitoring. Both allow for accurate dose delivery to the target area, decreasing the harm to surrounding healthy tissues.
In addition, CyberKnife is useful in many other tumor treatments as well.
