The National Lung Screening Trial (NLST) released its main findings in 2011,1 concluding that the use of low-dose computed tomography (CT) to screen for lung cancer reduced lung cancer deaths by 20% compared with chest radiography.1,2 The subsequent publication of new lung cancer screening (LCS) guidelines may raise the public’s awareness of the clinical application of low-dose CT in screening,3,4 leading to increased demand for screening not only by individuals who meet the eligibility criteria recommended for LCS but also by those who do not. The present study documents early experience of LCS in terms of both intended and unintended uptake of low-dose CT at the population level.
