Wife's uncle 59 just died yesterday from stage 4 lung cancer that moved to his liver. He was a smoker and started spitting up blood about 6 months ago, so he quit smoking, too late to help him. If you use any tobacco products you need to quit for yourself and your family. Last memories of him for his family was looking at him in a hospital bed unresponsive dopped up on drugs to keep him comfortable just waiting to die. Not a pretty sight.
