bb. :-( So sorry you're going through this. God how I feel for you. Such a tough choice, but I agree-- risky or not, I'd want to take the chance, and a quick end over a slow painful decline would be my choice ANY day-- for myself or a loved one. I know how scary this is for you and your mum. Thinking of you and sending love & all the luck in the world-- I hope the operation is a success.
