Surgery to remove part or all of the prostate and some of the tissue around it. Nearby lymph nodes may also be removed. It may be done through an open prostatectomy, in which an incision (cut) is made in the wall of the lower abdomen or the perineum, or by using a laparoscope (a thin, tube-like instrument with a light and lens for viewing).
