Hi Ben,
I was 48 when diagnosed, Gleason 3+4 T3b so a bit further progressed. I was suggested surgery by one surgeon, then RT/HT by another! (I went RT/HT) What swayed it for me was I was told surgery would be none nerve sparing and I would more than likely need salvage therapy.
It seemed like a double wammy of side effects!
I'm one year on from EBRT and HDR Brachytherapy and have about 8 months left of HT. Side effects from HT haven't been too bad, but will be glad when I'm off it!
Had the cancer been more contained I think I would have chosen the surgery route. However I'm happy with my choice and remain functional, more so hopefully once off HT!
Prognosis is pretty the same either way. Side effects so far have been mostly HT related which will hopefully ease off once it finishes. RT side effects reduced slowly over about 6 months or so. There are potential long term effects. slight increase in other cancers in this area, very slight though. ED can set in as can urinary strictures, but these can also occur with surgery.
Choosing which route to take was the most difficult part of all this, however I did fell a lot better once I had.
All the best
John
