Summary

This study follows 338 adults with two or more ground glass opacities (GGOs) in their lungs. Instead of immediate treatment, doctors monitor the spots with regular CT scans to see if any turn into lung cancer. The goal is to collect information that helps understand these spots and improve future care.
