My brother at 77 had five sessions of SBRT radiation. His PSA has pretty much settled down in the three years since. He did have small cribriform And it doesn’t seem to make a difference.

At your age, there’s no reason you need to have surgery, SBRT radiation is very common.

See what the pet scan shows, If it is clear then that’s probably all you need.

They did give him ADT for six months because he had a Gleason 4+3. The only problem that caused was some hot flashes. The radiation caused some cystitis and he had to take Flomax every other day for a couple of months, but then everything cleared up.

You don’t mention anything about your diagnosis, That could make a big difference. What was your PSA? What was your Gleeson score? Did you have a decipher test?
