The cyberknife technology for prostate cancer consists of a robotic arm, which is controlled by a computer. The computer dictates angles of radiation and gives focused treatments, sparing the delicate surrounding tissues. It allows for tracking of the target with seeds, which is the only form of radiation to achieve this. It provides unparalleled accuracy and can allow for the acceleration of doses.
There are low secondary side effects, such as rectal/bladder cancer malignancy, incontinence, impotence and low morbidity, which is better than other forms of radiation. The total dose is less than half of the standard dose, but since it's given in 5 days, it is much more powerful.
