In brief: Many things
>80% of lung cancer is caused by smoking.
However never smokers (defined as <100 cigarettes in lifetime) can get smoking. Risk factors include radon exposure, second hand smoke, and genetic mutations such as egfr activating mutations.

In brief: Possibly genetic,etc
Nonsmokers account for 15% of lung cancer cases, and these cases are often due to a combination of genetic factors, radon gas, asbestos, and air pollution including secondhand smoke.
Asbestos can also cause mesothelioma, a cancer of the pleura or lining on the surface of the lungand diaphragm. The main type of lung cancer in nonsmokers is adenocarcinoma, particularly bronchoalveolar carcinoma.
