Air pollution-linked blood changes detected years before lung cancer diagnosis

medicalxpress - A new study, published Tuesday in Nature Communications, found measurable changes in people's blood associated with exposure to air pollution and the subsequent development of lung cancer. The findings provide promising clues that could help shape future …

AI Summary: New analyses link long‑term air pollution exposure to distinct blood metabolic and biomarker changes that appear years before lung cancer diagnosis, suggesting a window for earlier detection. The work identifies candidate pathways tying inhaled pollutants to carcinogenic processes and proposes blood‑based signals for future screening or risk stratification.
