Blood markers linked to pollution signal future lung cancer
A recent scientific study has found that measurable changes in the blood of individuals exposed to air pollution precede the diagnosis of lung cancer by several years. The study's results indicate that air pollution is a carcinogen and leads to disturbances in vital processes such as inflammation, oxidation, and energy metabolism. Although smoking remains the most significant risk factor, many cases of lung cancer are diagnosed in non-smokers, highlighting the importance of air pollution and its role in the disease. The study emphasizes that early detection of changes in blood metabolites associated with pollution can contribute to the development of biomarkers for early diagnosis. This approach could enhance future prevention and screening strategies, underscoring the need to consider environmental factors in assessing the risk of developing lung cancer.
