So sorry, Wade. Though, it would help a lot, for your dad, if you would fight for it too, show him that your willing to be positive along with him, it'll help him a bunch, i am sure.
Sorry to hear that. Your dad and your family are in our prayers. My Mom just beat cancer after a 4 month fight with it. Attitude goes a long way in beating this, glad to hear he is ready to fight it.
