Lung<unk> -cell carcinoma is the second most common histologic type of lung cancer after adenocarcinoma, reaching 22.6% of all lung cancer cases as of 2012. The relative incidence of the former has been steadily decreasing in favor of the latter due to the decreasing smoking rates in the last few years. As much as 91% of lung SCC has been found to be attributable to cigarette smoking. Incidence is greater in men than in women.
