Getting it done now is YOUR choice, not your doctors choice - but it may be their recommendation. Get the Decipher test so you at least know if you are in the aggressive category or not and that will be some peace of mind for you but also more information for determination of treatment.

I completely understand where are you coming from. You just got results and all of this now looks daunting, overwhelming and scary. But your results show very early changes so you can take time to do research, seek other opinions and think about everything with no rush. The AS that your team proposed is very active - remember, my husband had MRI every 2 years and had one single biopsy 2019 and none till 2025. His PSA was going up and down in that period so it was not the perfect parameter. MRI actually showed his lesion in the right lobe getting smaller and guess what - that lesion went berserk. But, my husband is not a typical case and he had bad doctor, so please do not let it be good example for you. I am mentioning his case just so you make sure to have your prostate checked regularly and OFTEN. Your team made great AS plan, in my opinion, remember my husband did not have anything like that. You definitely have 6 mos to think about it all, at least about what treatment would be the best for you. Than you will have another biopsy and/or treatment, you have time to think it over. You seem to be in good hands and I am sure that they would understand if you choose treatment sooner rather than later. You have many options at this point and I am sure that all will be well in the end.
Wishing you the best of luck with whatever choice you make.
