Lung Cancer Screening at a Military Treatment Facility: A Retrospective Review.

Introduction: Lung cancer is the leading cause of cancer death among men and women, accounting for more fatalities than colon, breast, and prostate cancers combined. Smoking causes about 85% of all lung cancers in the United States and is the single greatest risk factor. In 2013, the US Preventive Services Task Force (USPSTF) published initial guidelines for low-dose computed tomography lung cancer screening (LCS) among patients 55-80 years old, with a 30-pack-year history, who are current smokers or who quit within the previous 15 years.
