Inspiring: Teen Plays Football After Beating Brain Cancer

Zach Lederer almost died of a brain tumor when he was 11. Now, after battling cancer, relearning how to walk and regaining the life no one thought he would have after his diagnosis, the 17-year-old is tearing up his high school football field.

Lederer tells CNN he faced the field in honor of all the other kids he knows are struggling to survive:

"It's kids like these who inspire me to get back up after every play...I'm not only playing football for myself; I'm playing for all the kids who have never had the chance to play due to illnesses."
