Feedsack, welcome to Healingwell.
First, and , there is no right or wrong answer, only the answer that is right for you.
With that said, is there evidence on the MRI of the cancer having escaped the capsule? If so, or if the surgeon thinks its in a tough place and you need to be prepared for possible positive margins, poor pathology, you might think twice about
surgery, since that brings the possibility that after surgery you might need radiation anyway. (Which is always a possiblity, see my signature).
Its important for you to educate yourself as much as possible. There are books by Dr Patrick Walsh
https://www.amazon.com/patrick-walshs-surviving-prostate-cancer/dp/1455504181 and Dr Mark Scholz
https://www.amazon.com/invasion-prostate-snatchers-essential-managing/dp/1590515153/ref=sr_1_2?dchild=1&keywords=mark+scholz&qid=1611253741&s=books&sr=1-2 That will help you. Others here will chime in with more extensive information as well.
Understand the side effects, understand the chance of cure for each of the treatments, understand the different types of radiation.
As far as radiation +ADT, i had both, and i had ADT for 6 months. Its not fun, but it was very manageable at least for me. Everyone is different. But 4 months shouldnt be too bad. With a 4+3 Gleason i think most if not all Radiation Oncologists would strongly recommend ADT as part of your treatment.
Good luck, stay tuned for more responses, and please keep us posted.
