First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study is testing a blood test that looks for tumor DNA to see if it can more accurately tell whether a lung nodule found on a CT scan is cancer. About 590 people getting lung cancer screening will give blood samples and be followed for 3 years. The goal is to improve how we decide which nodules need further testing, reducing unnecessary procedures.
