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.
