Hi Mack,
I totally get where you are coming from. I'm in sort of the same situation.
After initial diagnosis, I decided on AS, and 18 months on still keen to continue this (if they allow it). At my recent clinic visit to discuss the latest biopsy results, the nurse mentioned the consultant has been very keen for me to come off AS and take radical treatment.
The 1st biopsy 18 months ago identified as Grade 2 T2 N0 M0. The recent biopsy was a template, but not exactly. My prostate at 26cc was too small for the template so it was done manually to replicate the template.
Cutting to the chase, at the clinic the nurse stated its very unusual in her experience, but I am now showing as Grade 1 with less than 5% of the sample tissue showing adenocarcinoma. They are not dismissing the earlier Grade 2, but latest samples are different. However they do keep reminding me, these are only samples and its very easy to miss the PC.
For me the AS has not really messed with my mind too much. I'm very much in favour of quality of life. But should I find myself having to make a treatment decision, I'm currently leaning towards 5 session SABR with no HT, that is if I can get the necessary referral to a hospital that will do this, and if they find me a suitable candidate. If I have to pay privately for a SpaceOAR thats fine, its a no-brainer I wouldn't even consider it without that.
The whole situation may well change and options or decisions might not play out this way.
This forum is amazing and very informative, but I do also know personally people who have had RP and some who have had RT. I've heard good and bad from both options, so its very difficult to apply this to your own situation as clearly every outcome is only every going to be unique to that person.
