I had one done and one plug sample was positive. I felt no pain. Went to Johns Hopkins and had my prostate removed. The surgeon had done over 25K of the surgeries by hand and got the same results as a good doc with the machine. A friend had the needle biopsies taken and no cancer was found but the test checking the semen showed the antigen for cancer so he had his prostate removed. Every slice tested by pathology was positive for cancer. His doctor told him he could wait and see and he chose not to. The doctor told my friend he obviously made the right call!
