I'm glad you have been able to come to a decision. I know that evaluating and discussing the alternatives is stressful and coming to a conclusion should (hopefully) take a weight off your backs.
Brachytherapy is an excellent treatment with cure rates as good as surgery, so I'm sure hubby will be just fine. If you want some recent perspective on "what happens" with the procedure, check out "Tudpock's Brachytherapy Journey" on this forum.
One recommendation I have at this time: The only real discomfort I have had thru the entire process was the volume study (check my post!). I had this done with no sedative or pills...and this is the only thing I would change. I don't think he needs to be totally sedated, 'cause it's not that bad. But a little Valium or equivalent would make for a better experience.
Let me know if I can be of any help and good luck.
