Toward More Effective Lung Cancer Risk Stratification to Empower Screening Programs for the Asian Nonsmoking Population

Abstract

Lung cancer is currently the leading cause of cancer-related deaths worldwide, although the smoking rate in the global population has gradually declined over time, and tobacco companies with official statements worldwide aimed to prevent smoking initiation among school-aged children in the 1980s [1]. Recently, an estimated microsimulation model demonstrated that the incidence of lung cancers caused by smoking has decreased with policy controls [2,3]. However, the absolute number and proportion of nonsmoking lung cancer in the population is estimated to gradually increase over time in the United States, projected from 2015 to 2065 [1-3].
