That’s because the computer-assisted technology allows doctors to be more precise in operating the affected area, while sparing surrounding nerves and other tissues, which when cut or damaged, can lead to impotence, incontinence, and other complications. That in turn, reduces the risk for follow-up treatments, such as radiation, chemotherapy, or hormone treatments. Cancer patients who undergo robotic-assisted surgery have fewer cancer cells at the edge of their surgery sites, less need for additional treatments, and fewer complications than patients who have open surgery.
