Not an EBRT expert, so not chiming in. Also, not an expert at staging, but I think a PET scan identification of "aggressive" cancer just indicates that is active cancer and is not the same as a Decipher test, which actually looks at the cancer cells from the biopsy samples and is a better gauge of whether cancer is aggressive or not.

Others who know more, please chime in.

Super glad to hear your older brother is doing well!

Suspect that if prostate cancer runs in the family, genetic testing is a good idea and perhaps if you have sons, to have them start screenings at an earlier age. Stuff I think about as a dad with a son.
