New study links air pollution to increased breast cancer risk

Study, which spanned a 20-year period, found that 15,870 breast cancer cases were linked to air pollution

WASHINGTON – A new study in the U.S. has found a link between increased air pollution and an increased risk of certain breast cancer tumors.

The National Institute of Environmental Health Sciences and the National Cancer Institute analyzed data from more than half a million people from six states and two metropolitan areas.

The study, which spanned a 20-year period, found that 15,870 breast cancer cases were linked to air pollution.

The study focused on PM2.5 pollution, which consists of tiny particles from industrial emissions and vehicle exhaust that can penetrate deep into the lungs.

These particles are known to exacerbate respiratory problems, cause cardiac arrhythmias and trigger non-fatal heart attacks.

The study’s lead author, Alexandra White, emphasized the significance of the findings, pointing to an 8% increase in breast cancer cases in regions with higher PM2.5 exposure.

“Although this is a relatively modest increase, these findings are significant given that air pollution is a ubiquitous exposure that impacts almost everyone,” she said.

 Considering widespread air pollution, these findings underscore the possible link to breast cancer.

The researchers recommend further research into regional differences in PM2.5 exposure and its influence on cancer risk.
