Causative factor: Smoking, and some other carcinogens cause your own cells to be irritated, transform, then become malignant , and then grow a mass and then can metastasize in the process of cancer.

Increases risk: Only about 20% of lifelong smokers will develop lung cancer, so it doesn't cause cancer in everyone. Tobacco smoke interacts with genetic predisposition to lead to cancer.
