Abstract

The purpose of this article was to examine the relationship between a proxy measure of exposure to automotive exhaust – roadway density – and risk for adenocarcinoma lung cancer. Using data from the Kentucky Cancer Registry and the Kentucky Geoportal Data Clearinghouse, we conducted a cross-sectional study of the distribution of adult lung cancer cases by histological type across the state of Kentucky. The north-central region of Kentucky has a higher prevalence of adenocarcinomas and greater roadway density. Among adenocarcinoma cases in Kentucky, there are more non-smokers than other types of tobacco use. As smoking rates decrease in Kentucky, and elsewhere, environmental risk factors could be important to mitigate for ongoing prevention strategies.
