I think many docs have abandoned the 'finger' exam because of too many false positives and false negatives. Though far from perfect, the PSA test seems the most reliable. Assuming you're a male (j/k), by mid-life odds are you will experience the symptoms you've mentioned. You can read about Benign Prostatic Hyperplasia (BPH) at your leisure. Lastly, neither am I a doctor nor have I ever played one onstage. I have, however, had finger exams and PSA tests.
