smoking is recognized as the leading cause of lung cancer. not only the smoker, but also the nonsmokers who are suffering from the second hand smoke.

I think smoking is the main cause for lung cancer. My dad has lung cancer because he smoked 35 years.

Smoking is the main cause. Don't worry though, if you are a smoker, you can just deny it.

As far as I know smoking is the main cause of lung cancer. Also 'passive smoking' - breathing in second hand smoke from people smoking near you - is a bit cause of lung cancer. Other causes that I know of are asbestosis - having been exposed to asbestos fumes. Also maybe exposure to other harmful fumes such as working in a mine or certain factories.
