I can't remember the name of this movie?

I remember watching this movie when I was younger and all I remember about it was there was a little boy with a brain tumor in the middle of his brain and something about get well cards. It was a made for TV movie on a channel that used to be called PAX. I don't remember if it was a particularly good movie but it's kinda one of those things that I think about and it drives me crazy until I can remember. So if anyone remembers what it is that would be great.
