A comprehensive study conducted on millions of Medicare beneficiaries in the US suggests that long-term exposure to fine particle air pollutants (PM2.5) and nitrogen dioxide (NO2) might elevate the risk of non-lung cancers among older adults.

Led by researchers from Harvard T.H. Chan School of Public Health, the study underscores that over a span of 10 years, prolonged exposure to PM2.5 and NO2 could heighten the likelihood of developing colorectal and prostate cancers.
