@chaimkugel I also closely evaluated the position of my core 16 L1 - Left Posterior Apex Peripheral Zone that was 4+3; the other 5 cores with prostatic adenocarcinoma, 3+4, were all located in adjacent zones (the remaining 10 cores showed no cancer). You can then speak to ROs who, typically, don't delve into PCa position conversations without prompting. I found it highly useful to consult with a retired urologist friend who spoke to me under 'cone of silence' in addition to several other ROs and urologists who gave formal opinions largely representative of their institutions.

As has been mentioned, the Decipher Grid is one of the best predictive tools available and a PSMA PET can provide an additional layer of reassurance. As far as future treatments, that hopefully will never be needed, I am confident that with AI driven and other advancements, what we have available in 10 years will make the current offerings 'primitive'.

Best of luck to you! It was certainly reassuring to know that I did my best to evaluate alternatives.
