Breath of Danger: Unveiling PM2.5’s Stealthy Impact on Cancer Risks
Kefah Mokbel
Abstract
This article explores the intricate relationship between airborne particulate matter (PM), specifically PM2.5, and its profound impact on human health, emphasising the heightened risks of cancer. Examining the composition and characteristics of PM2.5, such as particle size and surface area, reveals its ability to induce inflammatory injury and oxidative damage. The carcinogenic potential extends beyond respiratory implications, affecting various organs, including the digestive tract, breast, and prostate. In addition to the genotoxic effects of PM2.5, attached polycyclic aromatic hydrocarbons are recognized to be endocrine-disrupting chemicals with specific implications for breast and prostate cancer. Long-term exposure to PM2.5 is associated with increased cancer mortality, with specific risks identified for different cancer types. The linear correlation between cancer risk and PM2.5 concentration calls for a re-evaluation of permissible emission levels. The article concludes by proposing specific mitigating strategies for individuals exposed to elevated PM2.5. It suggests antioxidant-rich diets and supplements, and exploring inhalation-based antioxidant administration as potential protective measures.
