Overview
Epidemiology and Demographics
Squamous cell carcinoma accounts for ~30-35% of all lung cancers and in most instances are due to heavy smoking. Historically it was the most common type of lung cancer but in many countries has gradually declined over the past four decades with a rise in adenocarcinoma of the lung, which is now the most common in many series 4.
In general, squamous carcinomas are encountered more frequently in male smokers, and adenocarcinoma in female smokers, although these results vary from series to series.
