Is non-small cell lung cancer often a non-smokers cancer?

Yes: The two variants of lung cancer that are non small cell (neuroendocrine) in origin are squamous and adenoCa of the lung. In the last decade, the squamous variant has taken a back seat and adenoCa unrelated to smoking has occupied more than 70% of the cases. The probable cause is a viral factor.

Yes: There are several types of non-small cell lung cancer. Typically squamous cell is associated with smoking. Adenocarcinoma isn't usually related to smoking.
