uspstf lung cancer screening :: Article Creator Vapers May Be Less Likely To Undergo Lung Cancer Screening E-cigarette use among individuals eligible for lung cancer screening was independently associated with a reduced likelihood of screening, a cross-sectional study of U.S. Adults revealed. Compared with those who never used e-cigarettes, current vapers had a lower odds of ever undergoing lung cancer screening (OR 0.79, 95% CI 0.62-1.00) and of being up to date on screening (OR 0.67, 95% CI 0.51-0.88), reported researchers led by Qian Wang, MD, MPH, of Case Western Reserve University in Cleveland. The associations were more apparent for former (rather than current) smokers of traditional cigarettes. For individuals who previously smoked, those who used e-cigarettes appeared less likely to have undergone lung cancer screening (OR 0.73, 95% CI 0.52-1.04) and had a 46% lower chance of being up to date on screening (OR 0.54, 95% CI 0.37-0.80
