Study Links Air Pollution to Early Lung Cancer Biomarkers

Medical experts warn that prolonged exposure to traffic fumes and indoor smoke from solid fuels causes cellular damage similar to the effects of smoking.

Repeated inhalation of fine particulate matter leads to inflammation and oxidative stress, which researchers identify as early biomarkers increasing the risk of lung cancer.

Doctors recommend improving kitchen ventilation, using cleaner cooking fuels, and wearing masks in high-pollution areas to mitigate long-term respiratory damage.
