Pre diagnosis function considerations

My research starting down this road is leading me towards some conclusions to bounce off others here. I have been on AS for about 4 years and this December biopsy confirmed cancer. 3+4 slow growing, low involvement, favorable. Biopsy was random perineal with 12 cores so how conclusive? My psa has been fairly steady but on higher end at 7.5-8.8 range. I feel like it was time to start treating it and seems maybe waiting a bit too long. Back to topic: The last 4-5 years I have had mild urinary symptoms, mild urgency and mild dribbling, decreased stream. Getting up once a night. sometimes not, what I considered aging and could live with. Has very gradually gotten a bit worse over that time. Prostate is somewhat enlarged at 51cc.
So looking at surgery vs different radiation treatments. Seems with some existing but fairly mild urinary issues, enlarged prostate, also throw in my hip implants which complicate imaging for the more advanced techniques, including even psma scans to some extent. Maybe radiation is not as favorable? Anyone one here with similar stats, body parts, some milder previous symptoms that took them into account when making their decision? Thanks , sorry got a bit long.
