‘But I Never Smoked’: A Growing Share of Lung Cancer Cases Is Turning Up in an Unexpected Population

January 26, 2021

(STAT News) – A 2017 study of 12,103 lung cancer patients in three representative U.S. hospitals found that never-smokers were 8% of the total from 1990 to 1995 but 14.9% from 2011 to 2013. The authors ruled out statistical anomalies and concluded that “the actual incidence of lung cancer in never smokers is increasing.” Another study that same year, of 2,170 patients in the U.K., found an even larger increase: The proportion of lung cancer patients who were never-smokers rose from 13% in 2008 to 28% in 2014.
