Research finds that the higher the levels of air pollution in a region, the more cancer-promoting mutations are present
Air pollution has been linked to a swathe of lung cancer-driving DNA mutations, in a study of people diagnosed with the disease despite never having smoked tobacco.
The findings from an investigation into cancer patients around the world helps explain why never-smokers make up a rising proportion of people developing the cancer, a trend the researchers called an “urgent and growing global problem”.
