title: Computed tomography screening for lung cancer: where are we now?
abstract: Low-dose computed tomography (LDCT) screening has been shown to result in detection of earlier-stage lung cancers, with a 20% reduction in cancer-related deaths. LDCT screening offers significant potential benefits to selected patients; however, many questions remain, including questions about the applicability of lung cancer screening in clinical practice.
