I think you have a couple different issues here: one is his health, one is your place in his health (can't quite find a way to say that). I mean, he is an adult and can chose what he does next. we all have had problems with loved ones who try to gently push us to do something more or different...I, for one, don't love that! I want my loved ones to allow me the freedom and respect that shows I am smart enough to do what seems right at the time. it is fabulous to want to help, it just is a delicate issue. as was mentioned by others, each new doc, treatment, test takes SO much out of a person who is already ill, so these suggestions aren't often welcomed.
