Health Desk--2 November 2017: A new study shows that air pollution can increase the risk of death from kidney, bladder and colorectal cancer besides causing lung cancer.

Air pollution represents a complex mixture of a broad range of carcinogenic and mutagenic substances that may play a role in chronic systemic inflammation, oxidative stress and DNA damage in tissues that could ultimately prove fatal, according to researchers.

Lead author Michelle Turner, researcher at the Barcelona Institute of Global Health (ISGlobal) in Spain, said, “This research suggests that air pollution was not associated with death from most non-lung cancers, but the associations with kidney, bladder and colorectal cancer deserve further investigation.”

Over 43,000 non-lung cancer deaths were registered among the participants. PM2.5 was associated with mortality from kidney and bladder cancer, with a 14 and 13 per cent increase respectively, for each 4.4 µg/m3 (microgram) increase in exposure.
