Judge orders teenager to continue cancer treatment, against desire of teen and parents

This case is weird. And we don't have enough information (such as, what's the teen's prognosis). But at first glance, there are obvious differences between this case and Terri Schiavo.

First off, Terri Schiavo was a vegetable and had zero chance. The doctors had already determined this without a doubt. We don't know what the prognosis is for this teen.

Secondly, Terri Schiavo and her husband (who could speak for her) were adults. This kid is a kid. Though his parents can obviously speak for him, but in this case his parents are on his side. Which one could argue makes this a more clear-cut case than Schiavo - no parent or guardian is arguing the other side here, they're all in agreement.

Third, does it matter how kooky the medical treatment is? Sugar-free cancer diet from a clinic in Mexico? Uh, okay. Then again, was the kid's prognosis horrible and he's trying anything he can as a last resort? If so, then his rationale for trying something radical is more sane and there's less a reason for the judge to intervene.

A very odd case, and we just don't have all the information (thanks AP) - what do you think?
