I agree with the sentiments of Brother Sonny's post above. With 2 cores, Gleason 6, low percentage, and low PSA, I would be comfortable at least doing additional AS. I don't feel that waiting another 6 months to a year would put your husband at any great risk. He is fortunate, that he should be able to choose when the time comes, the full spectrum of primary treatment options. With many of us, the choices were severely limited by our initial stats.
The Seeding, or seeding plus RT could be a good choice for him, even though I am a surgery guy. I wanted seeding, but didn't meet the critera.
Surgery is always the obvious treatment choice, and most popular by number, but as you well know I am sure by now, comes with the most risks of life changing side effects. Some men are lucky with virtually no incontinence, others battle with it for years. Some men, even with extensive nerve sparing ops, end up with perm. ED, while others, like me, won the "luck" raffle and suffered no ED with only a single nerve bundle spared. Point - you never know what you are going to get.
In my opinion, this is still the time to think long and hard about all of it, and talk to as many professionals as you have time and resources for, then when a decision has been made, you can live with it - before and after.
Good luck in any event,
