I fully sympathise with your situation, I'm 50 and had a PSA come back at 5.6 from a routine medical at work. I had no symptoms and I was convinced it was all a false positive and everything would be OK - until I had the biopsy (Gleason 3+4, T2a). I have two boys 13 and 16 and it completely blew my world apart for a while - which was hard as I still had to go to work and act as if nothing had changed.
I was as scared of the biopsy as I was of the possible result. I had a transperineal template-guided biopsy which a required a general anesthetic and apart from visits to A&E for sports injuries, I had never had hospital treatment or an operation. I need not have worried as I was in very good hands.
When I was diagnosed, the point my surgeon and urologist kept making and re-enforcing at every visit, was that I was lucky, it has been spotted early, treatments were available with excellent results. Their view was I needed to deal with it because it wasn't going away by itself. He also pointed out that there was nothing I could have done differently to avoid the cancer, i.e. I could not blame myself. Both of these points kept me going during the darker times.
I am now five months in to Brachytherapy and my first PSA was 0.9
I agree with the other posts - its best to know sooner. If you have PCa, it isn't going away and you will need to think about your treatment strategies. If you don't have PCa - what a relief!
