Lung Cancer - It's Not Only For Smokers!

Many people died of lung cancer because of so many reasons. My uncle died of smoking last 2 years ago. He smoke since he was young till the age of 40 he died. My father almost died of smoking too. He was smoking since he was a teenager but after 50 years of age something happened to him. We brought him in the hospital and found out that his left lung was already gone and the right just have very little left so he has the chance to live and live healthy without that smoking thing.
