PM2.5 has been identified as a carcinogen and lung cancer is the first

The 2013 China Climate Bulletin has recently announced that in 2013, the average number of foggy days in the central and eastern regions of China was 16 days, which was 8 days less than the average year, the lowest since 1961; the average number of days was 36 days, 27 days more than the average year, 1961 The most since the beginning of the year, Yutianchuang was the most in 52 years. The new word “nuclear fog and fog” mentioned in an article recently circulating in the Internet has caused public concern and hot discussion. Recently, experts believe that PM2.5 has been identified as a carcinogen. In this regard, Jiangsu experts believe that this theory is reasonable and it may be lung cancer.

Air pollution confirmed as carcinogen

According to media reports, Pan Xiaochuan, a professor at the Peking University School of Public Health, said that last month the International Agency for Research on Cancer (IARC) had identified air pollution as a carcinogen at the meeting in Lyon, which was also recognized by experts. In fact, specifically speaking, atmospheric particulate matter, also known as PM2.5, is a confirmed human carcinogen.

Dr. Chen Senqing, from the Department of Molecular Biology and Genetics of the Jiangsu Provincial Cancer Hospital, told reporters that although the etiology of cancer has not yet been fully elucidated, “PM2.5 carcinogenesis” is theoretically reasonable and bears the brunt of lung cancer, PM2.5 in the air. Only 1/20th of the hair is equivalent to the thickness of the lungs. It will precipitate into the alveoli in the lungs. It will not only damage the alveolar epithelial cells, but it will be difficult to remove. At the same time, PM2.5 absorbs a lot of harmful gases, heavy metals and carcinogens. These toxic substances will be deposited in the alveoli with PM2.5 and will directly produce toxic effects. Long-term exposure to PM2.5 will increase the incidence of lung cancer. From the clinical perspective of their hospitals, there are more and more patients with lung cancer. Although medical technology is advancing, lung cancer is still the biggest fatal cancer in Jiangsu.

Professor Song Yong, Department of Respiratory Medicine, Nanjing General Hospital of the Nanjing Military Region said that from a clinical point of view, there are more and more patients with lung cancer. In their wards, they once had a young high school boy who was only 17 when he became ill.

The reporter learned from the 2012 death spectrum in Nanjing that in 2012, 12,347 people died of cancer in Nanjing, and the cancer mortality rate was 195.65/10 million, an increase of 7.07% over the same period of 2011. The top three cancer deaths were lung cancer, gastric cancer, and liver cancer.

Don’t smoke it now.

With the superposition of air pollution and other factors, the incidence of lung cancer is getting higher and higher. Among them, lung cancer patients in many cities including Nanjing have become the largest cancer killer. Song Yong said that the statistics of lung cancer patients admitted to their department found that squamous cell carcinoma and small cell lung cancer patients directly related to smoking accounted for 30% to 40%, and 90% of the lung cancer patients were severe smokers. The smoking age is generally greater than 20 pack-years, that is, a pack of cigarettes smoked every day for 20 years. "So when everyone is concerned about smog pollution, don't forget to smoke the culprit of lung cancer." Song Yong said that smoking is still behind the scenes of lung cancer. So please don't smoke.
