Prostate surgery is not a very simple surgery and for some it's considered a major surgery.
However prostate surgery is less major than other forms of surgery and it's pretty safe to have prostate surgery done and the success rate of prostate surgery is pretty high.
My dad had prostate surgery to remove his prostate and he came out of it very healthy and had no complications although he was fearful at the time.
The doctor discussed it with him and us and said that the surgeon has performed thousands of prostate surgeries and not one of his prostate surgeries had any complications.
Now some other people who've had prostate surgery may have had complications but mostly it's pretty safe and if you have prostate cancer occurring then getting your prostate removed would be the best option.
Or if you have a history of prostate cancer in your family then having your prostate removed would also be a good idea to prevent prostate cancer.
