Surgery usually removes the entire prostate and surrounding tissues. This operation is called a radical prostatectomy. In the past, impotence was a side effect for nearly all men undergoing radical prostatectomy. But now, doctors can preserve the nerves going to the penis so that men can have erections after prostate removal. Incontinence, the inability to hold urine, is common for a time after radical surgery for cancer.
Most men regain urinary control within several weeks.
A few continue to have problems that require them to wear a device to collect urine. Another kind of surgery is a transurethral resection , which cuts cancer from the prostate but does not take out the entire prostate. This operation is sometimes done to relieve symptoms caused by the tumor before other treatment or in men who cannot have a radical prostatectomy. Radiation therapy uses high energy rays to kill cancer cells and shrink tumors. It is often used when cancer cells are found in more than one area.
