@deku you are anything but alone. I'm newly diagnosed myself and am also relatively young for this at 54, so I cannot offer much advice but what I can say is wait until the biopsy is done. Mine was done on October 1st, results the 2nd, Decipher 8 days ago. My concerns were pretty grounded until 8 days ago. The biopsy isn't fun and I don't wish to repeat it, but you might be in the lucky group of men who don't need to worry about anything yet (or perhaps ever). Even if you have cancer, it's still possible that nothing needs to be done about it.

My first prognosis was active surveillance until the Decipher negated that and pushed me into prostatectomy territory. I was fine with active surveillance and it's not uncommon to just simply monitor this slow growing cancer for years. So even if something is found, you may simply need to get it checked regularly to make sure it's not progressing. Yes that means more unpleasant biopsies but it's better than treatment.

Hang in there! The biopsy sucks and for a couple weeks after it's an adjustment to the after effects but it passes, and just maybe you'll be absolutely fine - even if you do have cancer!
