Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators would like to see if lung cancer screening with chest x-rays,computer aided detection (CAD)and a lose dose CT scan can detect lung cancer in early stages when it is more responsive to treatment. The investigators would also like to see if early detection will reduce the incidence of symptomatic advanced lung cancer compared to no screening in former and current smokers with or without a family history of lung cancer who are 40-75 years old.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The fight against lung cancer is waged on three major fronts: prevention, detection and treatment. Our goal is to determine if chest x-rays,computer aided detection (CAD)and a CT scan can detect disease earlier when treatment is more effective. If we improve the detection of disease, we will see if screening reduces the incidence of symptomatic advanced lung cancer relative to no screening in people at high risk to develop lung cancer.

Study Groups

all enrolled subjects

Intervention is chest x-ray and CT scan. The chest x-ray image is read first without computer aided detection (CAD) and then a second time with computer aided detection (CAD) the CT scan is read by one reader. Subjects are asked to contribute breath and blood samples.
