Hi K2, and welcome to the forum.
I think you are jumping the gun a little. While it's possible you have PCa, maybe even probable, it's by no means certain. It may be just an infection and not necessarily one that has obvious symptoms.
For your next PSA test, make sure you abstain from sex and bike riding for two days beforehand, and also make sure you have the blood draw before the DRE and not the other way round. Surprisingly some docs don't do this.
Generally higher PSAs mean more serious cancer, but not always so. Gleason 8-10s may not generate much PSA -- for example I was a Gleason 9 at biopsy but with a PSA of only 5.7.
As far as treatment options are concerned, from what we know so far, all options are
open to you. The actual treatment you receive will be very much determined by your next PSA and biopsy. Good luck -- lets hope this is a false alarm and we never see you here again
