Lung cancer is the leading cause of cancer-related death among men and women in the U.S. and worldwide. For many decades, lung cancer was the sole cancer among the deadly four without an evidence-based screening method for decreasing mortality. This changed in November 2011, when findings from the National Lung Cancer Screening Trial showed low-dose lung CT screening was more efficacious in reducing deaths in high-risk individuals than conventional radiography. As such, an ever-increasing number of health organizations now recommend this screening protocol. Lung Cancer Screening by Mark Parker and esteemed VCU Health colleagues, fulfills the dire need for a comprehensive guide explaining the crucial aspects of lung cancer screenings. The first two chapters lay a foundation with discussion of lung cancer epidemiology and risk factors beyond cigarette smoking.
