Not likely: The predisposition to develop lung cancer can occur in families, but there is no direct link between lung cancer and a specific genetic condition.

Yes: Although over 80% of lung cancer in the United States is caused by exposure to cigarette smoke (both first hand and second hand), some lung cancers are the result to certain mutations. For instance, mutations to the epidermal growth factor receptor (egfr) can predispose some people to lung cancer.

Possibly.: The most common cause is tobacco use/cigarrette smoking. This is most strongly associated with squamous and small cell lung cancers. But there are other kinds, like adenocarcinoma that are also common and it is unclear why. Many genetic mutations are aquired and due to smoking, but some may indicate genetic susceptability. More research is needed.

Non-smokers with lung cancer is still among the leading causes of cancer related death in the US. As stated by others, radon gas, and some degree of genetic susceptibility may play a role. We are not yet capable of detecting the gene(s) that result in susceptibility to lung cancer. We don't know what they are.

Lung cancer: Of all lung cancers 97% are smoking related. 3 % in non smokers. Regd the genetic basis of lung cancer, to the best of my knowledge, there is no genetic variant. Sonetimes we see several cases in families but still primarily it is smoking associated.
