2000 volunteers needed to help spot lung cancer earlier

This study collects samples and health information from 2,000 people with lung nodules to find the best way to detect lung cancer early. Participants must have a nodule at least 5mm wide and plan to have a biopsy, PET scan, or follow-up within 7 months. The goal is to improve how doctors identify cancer and guide treatment, but test results won't be shared with doctors or affect actual care.
