Published on November 12 in the journal Scientific Reports,the article entitled “Exposure to air pollution and incidence of head and neck cancer”, is the result of a collaboration between researchers from three American universities.
Although previous research has been conducted on air pollution, the study carried out by John Cramer and John Peleman of the Wayne State University School of Medicine, shows effects other than those linked to respiratory system cancers. “Head and neck cancer is a more difficult link to demonstrate, and its frequency is much lower than that of lung cancers, but because it also occurs as a result of smoking, like lung cancer, we wanted to explore all the links,” explains Dr. Cramer. “Presumably the link to head and neck cancer comes from the particles we breathe and how they affect the lining of the head and neck. »
Very small polluting particles
To carry out their study, the researchers used information from Surveillance Epidemiology and End Results (SEER), the United States National Cancer Databasefor the years 2002-2012. John Cramer observed the highest association between this type of pollution exposure and head and neck cancer after a five-year lag period. They focused on the PM2.5,…
