Lung cancer specifically is most often caused by smoking (radon is a rare cause - I haven't seen a non-smoking patient whose tumor was proven to have been caused by smoking). It takes 20 years of non-smoking for the risk of lung cancer to drop to the level of non-smokers. Some cancers are caused by repeated assaults on natural cells.
