Computed tomography screening for lung cancer.

Abstract

Cigarette smoking is the attributable cause for 90% of lung cancers. To complement preventative strategies, the advent of lung cancer screening programs targeted at prior and active smokers has been explored to reduce the mortality and morbidity of this lethal malignancy. In this article, we discuss the results of major computed tomography-based lung cancer screening trials, cost-effectiveness of screening, guidelines from major societies and future directions of the field.
