Summary

This study looks at whether low-dose CT scans can help find lung cancer early in people aged 40 to 80 who have never smoked. About 2,500 participants will fill out questionnaires, give blood and urine samples, and have lung function tests and CT scans. Researchers will track how many lung cancers are found and check if a risk prediction model works well.
