Abstract:Screening for lung cancer using low-dose computed tomography is an established means for early lung cancer detection in smokers, but the role of screening for never smokers is unclear. In the 13 lung cancer screening studies involving unselected never smokers, detection rates ranged from 0.1% to 1.1% and positive predictive values ranged from 0.4% to 4.5%. In three lung cancer screening studies involving selected never smokers, selection was based primarily on occupational asbestos exposure, environmental rado… Show more
