So sorry to hear. My grandfather passed away almost two months ago from a aggressive form of lung cancer, same thing his brother had. They both were very heavy smokers - smoked for what, 50 years! My grandpa quit in 99', did fine, did what he loved, play golf, etc. then last year he started to notice he couldn't breathe well and wouldn't go to the doctor, and two months ago, he was diagnosed lung cancer and survived for about 2 weeks after that. Smoking is awful, period.
