Kit, calling the foundation is a good start. They will not only have resources as far as who and where in the state to go, I believe they also have support groups and counseling services that may be useful.
Reading back through your last comments, it does sound like you're climbing off the ledge--which is what needs to happen. I can relate--if you like, click on the link called "my story" in my signature file, which may give you some insight. My father also died of advanced PC in 2004, so I knew some of what I didn't want to do.
The important thing is that PC, particularly in your husband's risk category is curable. We don't use words like remission in PC treatment, we either talk about
cure in the low and intermediate risk categories, or we talk about
long term management in the high risk categories. So the focus is on finding the treatment that will give a high probability of cure with minimal side effect risk.
You mention prostate anatomy--yes, it's complicated down there. We talk a lot in here about
side effects, particularly ED and incontinence--which are very common after treatment. I'll admit I'm one of the fortunate ones, who came through without major SE's. A lot of men aren't so fortunate. PC treatment, regardless of type, IS messing with a very constricted, very complex part of the male anatomy that has a lot of room for error. Side effect profiles do need to be researched.
Hang in there. Keep loving him. Your support of him goes farther than you'll know.
