This observational study is looking for better ways to find lung cancer early. Researchers want to identify special markers (biomarkers) in your body that could show if you have lung cancer, even before symptoms appear. You might be able to join if you are 50 or older and have a history of smoking, or if you are being evaluated for suspicious lung nodules. The main goal is to see if these biomarkers can help doctors diagnose lung cancer, which will be checked using CT scans and pathology reports. The study is currently unclear on its recruitment status and plans to enroll over 3600 participants.
