air pollution causes lung cancerThe findings outline how fine particulates contained in car fumes “awaken” dormant mutations in lung cells and tip them into a cancerous state. The work helps explain why so many non-smokers develop lung cancer and is a “wake-up call” about the damaging impact of pollution on human health.
“Globally, more people are exposed to unsafe levels of air pollution than to toxic chemicals in cigarette smoke, and these new data link the importance of addressing climate health to improving human health.” However, the biological basis for how air pollution causes cancer has remained unclear. Unlike smoking or sun exposure, which directly cause DNA mutations linked to lung and skin cancer, air pollution does not cause cancer by triggering such genetic changes.
“Clearly these patients are getting cancer without having mutations, so there’s got to be something else going on,” said Swanton, who is also Cancer Research UK’s chief clinician. “Air pollution is associated with lung cancer but people have largely ignored it because the mechanisms behind it were unclear.”
