NCT ID NCT07134426

First seen Nov 01, 2025 · Last updated May 05, 2026 · Updated 27 times

Summary

This study aims to understand why some former smokers remain at higher risk for lung cancer years after quitting. Researchers will compare how the lungs of 100 former smokers and never-smokers break down a chemical called phenanthrene. The goal is to see if former smokers process this chemical through more harmful pathways, which could lead to better ways to prevent or treat lung cancer in the future.
