PM2.5 has been identified as a carcinogen, and lung cancer bears the brunt

The 2013 China Climate bulletin recently announced that the average number of fog days in central and eastern China in 2013 was 16 days, 8 days less than normal, which was the least since 1961; The average number of haze days was 36 days, 27 days more than that of the normal year, the most since 1961, and the most in 52 years. Recently, the new word “nuclear fog dye” mentioned in an article circulated on the 1nternet has aroused great public concern and heated discussion. Recently, experts believe that PM2.5 has been identified as a carcinogen. 1n this regard, Jiangsu experts believe that this theory is reasonable, and lung cancer may bear the brunt< According to media reports, pan Xiaochuan, a professor at the school of public health of Peking University, said that the international agency for research on cancer (1ARC) had identified air pollution as a carcinogen at its meeting in Lyon last month, which was also recognized by experts. 1n fact, specifically, atmospheric particulate matter, the so-called PM2.5, is a confirmed human carcinogen Dr. Chen senqing, from the molecular biology and Genetics Research Office of Jiangsu Cancer Hospital, told the reporter that although the cause of cancer has not been fully elucidated, the theory of “PM2.5 carcinogenesis” is reasonable. Lung cancer is the first to bear the brunt. PM2.5 in the air is only 1 / 20 of the thickness of hair. 1nhalation of PM2.5 in the lung will precipitate into the alveoli, which will not only damage the epithelial cells of the alveoli, And it’s hard to remove. At the same time, PM2.5 adsorbs a lot of harmful gases, heavy metals and carcinogens. These toxic substances will directly produce toxic effects with the deposition of PM2.5 in the alveoli. Long term exposure to PM2.5 will increase the incidence of lung cancer. From the clinical perspective of their hospital, there are more and more lung cancer patients. Although medical technology is advancing, lung cancer is still the most lethal cancer in Jiangsu Province Professor Song Yong, Department of respiratory medicine, Nanjing General Hospital of Nanjing Military Region, said that from the clinical point of view, there are more and more lung cancer patients. 1n their ward, there was a young high school boy who was only 17 years old when he was ill the reporter learned from the 2012 death spectrum of Nanjing that in 2012, 12347 people died of cancer in Nanjing, and the tumor mortality rate was 195.65/100000, an increase of 7.07% over the same period in 2011. Lung cancer, gastric cancer and liver cancer are the three leading causes of cancer death smoking is now possible. incidence rate of lung cancer is increasing under the influence of air pollution and other factors. Many city patients including Nanjing have become the first cancer killer. Song Yong said that according to the statistics of lung cancer patients in his department, 30% – 40% of the patients with squamous cell carcinoma and small cell lung cancer are directly related to smoking. Among these lung cancer patients, 90% are heavy smokers, and the age of smoking is generally more than 20 pack years, that is, one pack of smoking every day for 20 years” Therefore, when we are all concerned about haze pollution, we must not forget that smoking is the culprit of lung cancer. ” Song Yong said that smoking is still the main culprit behind lung cancer.
