Biomarkers for Risk Stratification in Lung Cancer

This study is searching for blood-based biomarkers — measurable biological signals in the blood — that could help identify people at higher or lower risk of developing lung cancer before symptoms appear. Early detection of lung cancer dramatically improves survival chances, but current screening methods are imperfect. By studying blood samples from participants over three years and comparing them with who develops lung cancer, researchers hope to find reliable early warning signals. **You may be eligible if...** - You are 40 years of age or older - You can understand the study and provide written informed consent - You are willing to provide blood samples at required time points - You are willing to complete three years of follow-up visits and check-ins **You may NOT be eligible if...** - You have had an active non-skin cancer within the past 5 years - You are unable or unwilling to commit to the 3-year follow-up period - You cannot provide blood samples as required Talk to your doctor to see if this trial is right for you.
