Key Points Question Will relaxing the cigarette smoking criteria for lung cancer screening reduce race- and sex-based disparities and identify more lung cancers, without a considerable loss of efficiency? Findings In this cohort study of 43 521 individuals, changing lung screening criteria from 20 pack-years to 20 years of smoking was associated with an increase in the number of individuals who were eligible and reduced race- and sex-based disparities in eligibility, while maintaining diagnostic efficiency. Further expansion to individuals with 10 years of smoking or 10 pack-years continued to identify lung cancer in high proportions in this cohort. Meaning These findings suggest that the expansion of lung cancer screening eligibility to individuals with less smoking exposure may be justified.
