Lung cancer patients show higher microplastic burden in lungs, study finds

A Greek study of 100 patients undergoing bronchoscopy found microplastics in 70% of participants; those later diagnosed with lung cancer had a higher microplastic burden in lung samples than those without cancer. The findings are observational and do not prove causation, and researchers say more work is needed to determine whether inhaled microplastics contribute to lung disease or are simply retained differently in diseased lungs.
