Story summary

Lung cancer is increasingly affecting non-smokers, with alarming links to air pollution causing DNA mutations akin to those found in smokers. A study of 871 non-smokers uncovered a troubling connection: greater pollution exposure led to more mutations, especially in critical genes like TP53 and EGFR. Researchers are calling for urgent exploration into how air pollution fuels this deadly disease.
