@bens1 gave you good advise.

The Decipher test is an excellent test on aggressiveness of cancer. Your pesent Gleason score does not indicate it though. But for me the lesion found would be troublesome and I would get second opinion.

The PSMA is a test to see if cancer has spread to other areas. But if I read your post right you have not been diagnosed with cancer.

The PSA test would be in my opinion done more frequently under active surveilance to see if rising numbers continue. Your prostate with lesions and cores in it is not a happy camper.
