As mentioned, we need how many cores were positive and other things.

You don't mention if you want to maintain your sexuality as a preference. For me, I had to learn, tell each doctor you are married and your sexuality is important. If you don't tell them, they don't know, and they will over-treat at your expense. Be sure you understand and state this, it is important as urologist especially often assume once you hit 50 your sexuality is of no interest, which isn't how it works.

Your decipher is incredibly low = no genetic risk. I will say however, decipher has a handful of genes it tests, like 22 only. There could be 100 or 1000 genes involved so I consider decipher, which a number of doctors trust for some reason, to be just about bunk as far as science goes. You test 22 of 1000's possible genes involved in PCa, and proclaim a risk level, that is bunk science. So in my opinion decipher is not the best.

You have not only no BPH (enlargement) but one of the smallest possible prostate sizes one could have just about, so that makes any care you get easier.

Your doctor doesn't mention so many other treatments. There are many other possibilities. Usually doctors only mention what is in their system, or what they studied. There are more options than mentioned to you.
