Thanks alot, Charm. You know, my Dad is definitely smart enough to know that if he isn't getting enough nutrition/losing weight too fast he will need one. He is fully aware of that, and wouldn't fight getting one if it comes down to that. He just wants to try and do it without and all we can do is support his decision.

I really do like hearing all sides to this issue. I think it's good to be well informed. I do wish more people would post who have made it through treatment without one at all, although I realize there may not be many of you.

Thanks again, everyone.
