Background: Lung cancer is the second most common cancer and the leading cause of cancer death in the US. Yet, only 2-4% of Americans were eligible for screening reported obtaining chest CT screening for lung cancer. It is critical for both males and females to be aware of lung cancer screening for early diagnosis and treatment. The present study proposed to (1) explore levels of awareness and receipt of lung cancer screening and predisposing, enabling, and factors associated with receipt and (2) examine the relationship between lung cancer screening awareness and receipt of screening 
Methods: A quota sampling strategy was used to recruit 242 aged 50 and above at the 2016 Minnesota State Fair. Data were collected through self-administered survey. 
Results: Receipt of lung cancer screening was positively associated with age and number of routine doctor visits but was associated negatively with married or partnered status. Awareness of lung cancer screening was strongly linked to the receipt of lung cancer screening. Low awareness and low healthcare use were strongly linked to lower receipt of lung cancer screening. 
Conclusion: Improving awareness of lung cancer screening and increasing the number of routine doctor visits may encourage at-risk individuals to actively engage in preventive lung cancer screenings, which in turn can reduce mortality from lung cancer in the US.
