Sorry you've ended up here.
What lead to the internal exam?
A PSA test?
I'm not sure what internal exam this was, but I'm guessing a Digital Rectal Exam (DRE), and/or Cycstoscopy of urethra and bladder.
I don't think anyone can tell you much until you have the test results.
Have you got a Macmillan or Urology nurse assigned to you yet?
Has he been put on any treatment yet such as hormone therapy? (Doesn't usually happen until after biopsy results, but it can happen before in some cases).
