Robotic surgery is done in the same fashion as open surgical removal. The difference is that what originally required a large incision (from the belly button down to the pubic bone), now only requires 4 to 6 small incisions, each about 5 mm-12 mm in length. These incisions allow instruments to pass through ports (a hollow cylinder through which instruments can pass), keeping the surgeon's hands outside the patient.

Laparoscopic surgeries, in which a surgeon performs procedures through small incisions in the abdomen wall, have led to less invasive cancer surgeries with decreased pain and faster recovery times for patients. Because of the reduced size of the incisions, hospital stays are often shorter, with some patients even able to go home the same day.
