Great what Riley Heidt is doing to keep your son's spirits up. 
I find that the hockey players are such great people!
My son went through brain cancer at age 13, so I know the pain and anguish associated with having a child suffer from cancer. Connor is 22 now and just finished his now yearly MRIs this week...he's ALL CLEAR. He is now 8 years cancer free. 
Wishing you all the best. Prayers for your son.
