Air pollution may protect against skin cancer, finds new study – but the health risks are far more serious

Air pollution might protect against the most dangerous type of skin cancer, melanoma, a new study finds. However, it’s crucial to approach these results with caution and consider the broader context of air pollution’s effects on human health.
At first glance, the study’s conclusion is surprising. It showed that higher levels of particulate matter (PM), so-called PM10 and PM2.5 with the numbers 10 and 2.5 referring to the size of the actual air pollutant, may have a protective effect against melanoma.
The researchers found that increased exposure to these air pollutants was associated with a decreased risk of developing melanoma. It’s important, though, to understand the limitations of this study and why we shouldn’t rush to embrace air pollution as a potential shield against skin cancer.
