I hope he can recover. My prayers will definately be with you and him. My great aunt has been battling lung cancer for over six months and they thought their would be no chance for a cure because it was too severe. Now she has lived past the time they gave us and we continue to pray for a miracle.
Thats the problem with cancer, you have to catch it very early or your in trouble. Lung cancer is one of the worst, only a 15 - 30% cure rate.
