Study: air pol­lu­tion linked to oral can­cer

The Sunday Guardian - - Nation -

TAIPEI: Higher lev­els of air pol­lu­tion may be linked to a height­ened risk of de­vel­op­ing oral can­cer, which in­cludes can­cers of the lips, tongue, cheeks, floor of the mouth, hard and soft palate, a study has found. “This study, with a large sam­ple size, is the first to as­so­ciate oral can­cer with PM2.5... These find­ings add to the grow­ing ev­i­dence on the ad­verse ef­fects of PM2.5 on hu­man health,” said re­searchers in­clud­ing Shou-Jen Lan, Pro­fes­sor at the Asia Uni­ver­sity, in Tai­wan.

Pre­vi­ously, high air pol­lu­tion has been linked to a host of health prob­lems, from an in­creased risk of de­men­tia to asthma and even changes in the struc­ture of the heart, with re­cent re­search sug­gest­ing there is no “safe level” of air pol­lu­tion.

For the new study, pub­lished in the Jour­nal of In­ves­tiga­tive Medicine, the team dis­cov­ered the as­so­ci­a­tion by look­ing at air pol­lu­tion data from 66 air qual­ity mon­i­tor­ing sta­tions in Tai­wan, col­lected in 2009.

They com­bined this with data from the health records of more than 4,80,000 men aged 40 and over from 2012-13.

Ac­cord­ing to the World Health Or­ga­ni­za­tion (WHO), air pol­lu­tion is re­spon­si­ble for an es­ti­mated 4.2 mil­lion pre­ma­ture deaths world­wide per year.
