Gulia, While I agree with Gary's statement about pain control, I have to say that at age 77, your Dad has earned the right to say "ENOUGH is ENOUGH". He is suffering now, and it will probably be a long time, if ever, before he is pain free. At his age, he should get to choose what quality of life means to him - and his family will need to respect that decision, tough as it may be. I don't mean to be insensitive, but sometimes we have to let our loved ones make the call. [I am speaking from experience with my Mom] It is tough. Amy
