"Fine dust, increased mortality rate by cancer" … First identification: Beads N

Research shows that prolonged exposure to air pollution increases the risk of death from all types of cancer. In particular, exposure to air pollution has shown a higher mortality rate in early-stage cancers than in terminal cancers.

The results of this study, which is the first study to examine the effects of air pollution on overall cancer mortality, were conducted by Professor Kim Hong-bae of the Department of Family Medicine at Myongji Hospital. Hanyang University and Professor Yong- This is the result of a comprehensive badysis of 30 studies on the risk of air pollution and cancer deaths.

According to Myungji Hospital, the meta-badysis will be published in the November 2018 issue of the International Journal of Environmental Research and Public Health (ICS).

The probability of cancer deaths is 17%, 9% and 6%, respectively, when ultrafine dust particles with a diameter of less than 2.5 μm, fine particles with a diameter of less than 10 μm and nitrogen dioxide increase of 10 μm / "He said.

In addition, the detailed study, divided between the mean concentration of air pollution, the stage of progression of the cancer, the level of methodological quality of the included documents and the smoking status of the subjects of the survey, showed that the risk of death cancer due to long-term exposure to air pollution increased significantly. It was badyzed.

In addition, the lung cancer mortality rate and the cancer mortality rate other than lung cancer were badyzed. Ultrafine dusts, liver cancer, colorectal cancer, bladder cancer, kidney cancer, fine dust have also increased the mortality rate of pancreatic and laryngeal cancers.

In particular, exposure to air pollution has not only resulted in an increase in end-stage cancer mortality, but also an increase in early cancer mortality rates.

Professor Kim Hong-bae said, "Previously, only a 10% increase in ultrafine dust had resulted in a 9% increase in the incidence and mortality of lung cancer." This study examined the effect of air pollution on overall cancer mortality "As a first study, we have shown that the accumulation of exposures to air pollutants increases the risk of almost all types of deaths by cancer. "

Professor Kim said, "Air pollutants increase oxidative stress and inflammatory responses, which can damage the genes in our bodies." In order to prevent cancer, we must take care of the whole country for pollution. "
