Air pollution linked to colon, prostate cancers beyond lung disease risk

Thousands of additional cancer cases annually in the U.S. linked to air pollution exposure, with disproportionate impact on low-income and Black communities.

A Harvard study spanning millions of Medicare recipients has found that the invisible air shared by entire communities carries a risk far wider than lungs alone — linking long-term exposure to fine particulate matter and nitrogen dioxide to colon, prostate, and other cancers. The mechanisms are not mysterious but biological: chronic inflammation, oxidative stress, and impaired cellular repair, processes that do not respect organ boundaries. What makes this finding quietly urgent is that the risk persists even in areas the government considers safe, and that it falls most heavily on those least
