Accommodation in cities filled with smog, increases the risk of developing cancer of the oral cavity in men by 40%. This is the conclusion reached by researchers from California.
Scientists of California, Quest Diagnostics Nichols Institute found that air pollution increase the likelihood of men to deal with cancer of the oral cavity. According to researchers exposed to high levels of harmful particles from factories and exhaust gases men are 40% more likely to develop this type of cancer. Recently in the countries large cities which suffer from smog, began to experience elevated incidence of cancer of the oral cavity. Particularly high rates are seen in Southeast Asia, which is experiencing an industrial boom.
Magicforum recalls that traditional risk factors for these cancers are Smoking, alcohol consumption and chewing of betel – a combination of nuts and leaves of the same plant. Risk factors also include the effects of heavy metals and emissions of chemical plants. But the California scientists say that for the first time linked the amount of fine particles in the atmosphere with cancer of the oral cavity. They believe that the key factor is contained in the air high levels of ozone, which is considered a key component of urban smog.
In the study, researchers observed the level of air pollution in different cities of Taiwan, a number of tumors, the health indicators and the database of insurance companies, ensuring payment of treatment. They analyzed the indicators of a variety of pollutants, including carbon monoxide, nitrogen oxide, nitrogen dioxide, ozone and sulphur dioxide measured in 2009 on 66 points in Taiwan. Then the scientists compared the records for the state of health of almost half a million men aged 40 and older that have shown a direct link between air pollution and cancer of the oral cavity.
