Hughes BD, et al. - In view of previous studies that correlate poor air quality with lung cancer development, researchers examined all Texas counties for the correlation of air quality indices with the development of lung cancer. Using data from the Texas Commission on Environmental Quality and the Texas Cancer Registry, they obtained lung cancer incidence, air quality indicators (particulate matter <2.5 μm, radon levels, oil well density), and known risk factors. Increased incidence of lung cancer was observed in correlation to 2.5 μm, but not to radon levels. No significant association of air quality indicators with an advanced cancer diagnosis was observed. Identification of areas with high-risk may guide strategies such as implementating targeted lung cancer screening programs.
