I have been around Kids cancer wards way way too much. I will say this. It has been my experience that the Doctors and Nurses involved in childrens cancer treatment are the unsung heros of the world.
They see diseases that are diabolical and evil and resilient and they fight and fight and win far more than they ever lose. When they lose, they lock them selves in closets and cry their hearts out. Every one I have met takes the battle with the disease very personal and not one I have met in many years has ever had the ego to say this is my Idea, I am going to win the Nobel for this, so i must keep this to myself. As soon as anything shows promise, it is talked about and spread about.
Yes, kids who fight cancer grow old way to fast, having to tell your sixth grade teacher sorry, "I will not be in class today as I have another funeral to go to" will do that to you. When your son or daughter has a memorial picture board in their bedroom with pictures of horribly sick kids they will never play with again on the wall it is easy for some to just say, "that's it. I am done."
As for the kid in this situation. I am not sure of all the details, the MSM loves to push the heroic kid angle, but it has been my experience too that the Medical Staff's rarely take such positions without serious reasons why.
If the kid is not into the treatment, it rarely works. Cancer is one of the diseases that seems to be able to beaten by willpower, maybe it is just to kill it you must nearly kill the child, and hope the cancer dies before the kid does. But in my experiences I have seen kids give up, or to some accept the inevitable and they just seem to slide away. I have seen some kids nearly ground down to nothing who just spit in the face of the disease and come back to win, Lance Armstrong is one, although not a kid, his will power seemed to simply drive himself to outlast the cancer.
His name has nothing to do with it. His parents could have named him Pixie Twinkle Dust and he deserves all the support he can get and his parents will love him more than you can imagine, but there comes times when A) the doctors know best, and B) the patient and the parents know best. The hard part is telling when it is Situation A or when it is Situation B
