Oral Cancer: Air Pollution May Increase Risks

According to a new study in Taiwan, a high concentration of fine particles in the atmosphere could promote the development of oral cancer. Explanations.
Cancers of the mouth (which usually affect the lips, the inside of the mouth, the back of the throat, the tonsils or the salivary glands) usually occur after age 40, men being more concerned on average than women. Unfortunately, at present, 70% of oral cancers are diagnosed too late: the 5-year survival rate is only 50% .If tobacco and alcohol abuse are the two main factors risk, air pollution could also promote the development of oral cancer, according to a recent study published in the Journal of Investigative Medicine.To reach this conclusion, the researchers worked from medical data concerning 482 659 men aged 40 and over, living in Taiwan. These have been linked to reports on air pollution carried out in 66 locations in the city in 2009.Heavy metals and carcinogenic molecules in the atmosphereBetween 2012 and 2013, 1617 cases of oral cancer were diagnosed among the group studied. Unsurprisingly, smoking (as well as consumption of a local substance, Betel's quid) was a major risk factor, but scientists found that men living in areas with high levels of PM also Thus, a concentration higher than 40.37 ug / m3 of fine particles could be associated with a 43% higher risk of oral cancer – a link that could be explained, according to scientists, by the presence heavy metals and carcinogenic molecules among the particles present in the atmosphere. Additional studies are now awaited.To read: The e-cigarette destroys the cells of the mouth Oral sex: men at higher risk of cancer than women Cancer of the mouth: green tea fights tumor cells
