HopeLab, a California-based non-profit, is using video games to help kids fight cancer:

LOS ANGELES (Reuters) - Saif Azar, a 14-year-old video game fan, said a new title called “Re-Mission” helped arm him with the knowledge of how to fight cancer after he was diagnosed with Hodgkin’s lymphoma in 2003.

“It was perfect, actually. It helped me understand the things that were going on in my body,” said Azar, who started playing the game as part of a clinical study and continues playing today as he wraps up his treatments.

Roxxi, the main character in “Re-Mission,” is a gutsy, fully-armed “Nanobot” who seeks out and destroys cancer cells throughout the body.
