2 of the things to avoid before a PSA test are :-
"Ejaculation can raise levels. Some doctors recommend you sustain from sexual activity for 2 days prior to lab testing
Bicycle riding may raise levels (due to seat pressure on the prostate)"
There are other factors that can give rise to increased PSA which one cannot prepare for as you are doubtless aware. Sorry, can't answer about possible effect of fasting prior to PSA, perhaps your GP could advise.
As regards your future journey, I think any speculation here would be so vague and uninformed as to be unhelpful because different types of cancer can advance/mutate at different speeds in individuals. Sometimes it does not develop sufficiently to warrant any/further treatment at any point whereas sometimes it can develop quickly, perhaps in steps, to the point that an appropriate treatment is recommended. Even your consultant, who is in the best position to give an opinion as he/she knows your case best and has the advantage of intimately knowing many case histories and studies, may well struggle to provide a helpful answer to your question at this early stage.
