New Method to Differentiate Benign and Malignant Pulmonary Nodules.

This study is developing and testing a new method to distinguish between benign (non-cancerous) and malignant (cancerous) small lung nodules — spots found incidentally on CT scans — without requiring biopsy, using advanced imaging or blood-based markers. **You may be eligible if...** - You are 18 years or older - A CT scan has shown a lung nodule smaller than 3 cm that is scheduled for biopsy or surgery - Your ECOG performance score is 0–2 (generally good health) - Your blood counts and organ function are within acceptable limits **You may NOT be eligible if...** - Imaging already strongly suggests cancer in multiple locations - Your organ function falls below the required thresholds - You are unable to provide written informed consent Talk to your doctor to see if this trial is right for you.
