I lost a favorite Uncle early this year to lung cancer. He was a great guy, I feel for you. One thing to remember is that even though we usually think of our parents as very strong, put yourself in their shoes and remember that one of your parents just lost a sibling. It is often harder for them than they let on. I had to be very strong for my Dad when my Uncle passed.
Sorry man that sucks. Always hurts to lose a family member. My condolences. aint it too late to pray?
