Thanks for the info. Now I am really scared that the news the dr gives will not be good news. I know that he has not really tried to help himself, by continuing smoking, but I am very very close to him and hate to go and hear a bad prognosis. I am just almost dreading to go. I am hoping this has nothing to do with any sort of cancer, but also I want to be prepared for the worst. This cancer is a terrible terrible demon!! Oh well, thanks again.
