I'm sorry y'all are having to go through this. I know there are always risks with any kind of procedure but this could well save his life. He will be in my prayers. Please let us know what's going on when you are able.

I hope they can convince him to stop smoking -- though people go through this who have never smoked, smoking is bad for everything as far as health is concerned.
