One of the world's first lung cancer or a big country, "fog"

   Environmental factors in the induction, the incidence of lung cancer and mortality continued to rise trend. If we do not take effective control measures, 2025, our country will reach one million patients with lung cancer, lung cancer has become the world one big country.

   Experts suggest that, should the environmental governance, haze monitoring, pathology research, early diagnosis and health education starting multiple angles, Take Measures to reduce the risk of disease, improve the health of the people.

  Lung cancer incidence continued to rise as an important incentive for environmental pollution

  National Cancer Registry Center released the "2012 China Annual Cancer Registration" After 8500 people in 24 provinces nationwide statistical data and analysis show that China's newly issued 3.12 million cases of cancer each year, more than 2 million deaths, including lung cancer has replaced liver cancer , squat cancer incidence and mortality in the first place. Data from the National Health and Family Planning Commission statistics show that the incidence of lung cancer is currently at an annual growth rate of 26.9%, in recent decades, every 10-15 years, the number of patients with lung cancer will increase one times. The reason of the death of the third resident survey results also showed that lung cancer mortality in the past 30 years, an increase of 465%, the highest in China replaced liver cancer mortality.

  Studies have shown that smoking, environmental pollution, occupational exposure, and genetic susceptibility to chronic diseases such as lung is the leading cause of lung cancer. Although smoking is considered to be one direct cause of lung cancer in the first one incentive, in recent years a number of studies to show that, with the implementation of tobacco control measures, the incidence of lung cancer caused by smoking significantly control the upward trend, but was positively correlated with the environmental impact of lung cancer incidence rate occurs rapidly gained momentum.

  Second Affiliated Hospital, Zhejiang University School of Medicine, cancer treatment center recently for 2011 to 2013 and admitted to the center of all lung cancer patients diagnosed statistics. It was found that three-year period, the number of lung cancer patients admitted to hospital were 899 cases, 988 cases and 999 cases, which related to smoking in patients with squamous cell carcinoma is one straight remained stable at more than 230 cases, accounting for a declining trend . "The small cell carcinoma patients with mutations have a direct impact, environmental impact, but to 7 percent per year, respectively, accounted for 45.9% of the annual number of patients with cancer of the center, 51.6% and 58.3%." Hospital diagnosis of Lung Cancer Center Deputy Director, doctoral tutor wang Kai said.

  Earlier, the Chinese Academy of Medical Sciences Cancer Hospital at the hospital for 10 years, more than 15,000 cases of lung cancer cases were found after case analysis, pathological type of lung cancer do not appear significant change: In the past mostly squamous cell lung cancer, and now the proportion of adenocarcinoma larger. Involved in the study, Professor, Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences YangGongHuan said: "Small particles can enter the depths of the alveoli of PM2.5, and adenocarcinoma have one set of causal relationship."

  One the other indicators also confirmed from the side affects gene mutations and environmental causes of lung cancer: In patients with lung cancer, do not smoke or less exposure to secondhand smoke in the growing number of patients; at the same time, a slight decline in smokers , the case of the number of women smokers do not appear significant upward trend, the number of women with lung cancer has continued to increase.

 

  In Beijing, Tianjin and other haze-prone areas, the incidence of lung cancer was significantly higher than the national average. Beijing Cancer Prevention Office of the Deputy Lord 任王宁 that the incidence rate of lung cancer in 2002 in Beijing, 39.56 / 100,000 in 2011 rose to 63.09 / 100,000, far higher than the national average. Tianjin lung cancer incidence rate is about 60/10 million, or new cancer patients have 1/5 of patients with lung cancer, and showed significantly younger trend; male and female lung cancer mortality is ranked second in the country and One first place.

  PM2.5 multinational study confirmed a positive correlation with lung cancer

  Positive correlation worsening air pollution and lung cancer between fog and haze, has been confirmed many domestic and foreign experts and authoritative organizations.

  University of Ottawa told the US 50 states and Puerto Rico region of 180,000 non-smokers had a 26-year follow-up study, and found significant correlation between PM2.5 and lung cancer. Research data show that air pollution and lung cancer mortality is closely related to the generation and more serious pollution, the more lung cancer, the higher the mortality rate, whereas the less and lower. PM2.5 concentrations for each additional 10 micrograms per cubic meter, lung cancer mortality increased by 15% -27% of people with a lung disease itself higher lung cancer mortality.

  Studies suggest that the tiny particles in the air pollution can harm the lungs through inflammation and damage DNA, which may be the direct cause of lung cancer in non-smokers and death. The results of this study has been published in the International Journal of authority.

 

  IARC latest data show that patients with lung cancer deaths worldwide in 2010, there are 22.3 million people are directly related to air pollution. To this end, the World Health Organization was "outdoor air pollution" as a category one carcinogen in 2013, and to date it as "the most widespread carcinogens."

  "PM2.5 lung cancer increased with more and more relevant and directly increases the risk of lung cancer." Zhong Nanshan, China Academy of Engineering, said. To this end, two of the country from 2012 he began, and then one straight question PM2.5 concern and called for a nationwide launch of the PM2.5 monitoring as soon as possible.
 

  Take Measures to reduce lung damage

  Experts say, you want to effectively control the lung cancer incidence and mortality, get rid of "the world's first lung cancer one big country" hat, research, health care, environmental protection and other multi-sectoral work together to break the existing impasse, the introduction of effective measures to become a top priority.

  After years of development, environmental pollution problems have become increasingly prominent, and became the most vocal people, people's livelihood, and the high incidence of cancer gene mutations resulting situation is increasingly common. Zhang, vice president of the China Meteorological research trolling and other experts urged countries not only to be carried out as soon as possible, including air, water, soil, etc., census and monitoring environmental pollution, but also to the introduction of a strong, long-term energy conservation, Guantingbingzhuan, recuperate and pollution remediation measures to reduce the negative impact of environmental pollution on public health from the source.

 

  Fudan University School of Public Health, Environmental Health Department Director Song Weimin suggested that the state-level large-scale of lung cancer associated with pollution survey as soon as possible. He said that apart from sporadic throughout the investigation so far has not been on the causes of lung cancer, especially lung cancer and other diseases related to air pollution of large-scale screening. Lack of baseline data and correlation of the lack of research makes to reduce the risk of disease, control the rapid growth of cancer science and policy basis for the starting point.

   As the fog and haze "culprit" of fine particulate matter, PM2.5 dust mainly from vehicle exhaust, industrial emissions and emissions from construction sites and road traffic generated. Wang Kai said, PM2.5 can carry dozens of carcinogens, including polycyclic aromatic hydrocarbons and the prevalence of lung cancer significantly correlated.
 
   Cancer Hospital, Chinese Academy of Medical Sciences, said Shi Yuankai, studies show, PM2.5 lungs after being inhaled by the body, will directly lead to alveolar elasticity, function, and even induce pulmonary fibrosis, alveolar ventilation affect functionality. Over time, the decline in lung function and cause serious organic disease, and even lead to lung cancer.
 
   In addition, to promote early detection of lung cancer also reduce lung cancer mortality was also positive. At present, 80 percent of lung cancer patients at the time of discovery is late, the 5-year survival rate of only 13%, lung specialists, Zhongshan Hospital, Fudan University, Department of Respiratory Medicine Baichuan Ren main doctrine, "even if the treatment is taken positive measures, which prognosis is very poor. "in strengthening the lung cancer targeted therapy, the latest medical technology to support efforts at the same time, combined with the current health care system in our country almost three full coverage, conduct annual physical examination at the time of lung cancer screening for early detection, early treatment improve survival duration and quality of life of patients with a positive meaning. "In particular, about 40 years old to begin a comprehensive examination of lung health conditions, there are familial, often exposed to outdoor workers is the need for early inspection, periodic inspection." Second Hospital of Zhejiang Medical Center for treatment of lung cancer deputy Dingli  Ren said.
 
   Finally, the experts also called for by public health agencies and the media, to strengthen scientific propaganda, efforts to change the status of public awareness of the extent of low atmospheric pollution hazards, poor awareness of self-protection. Not only to prevent lung cancer from tobacco, to avoid fumes environment, but also to develop wear masks when traveling atmospheric haze pollution climate habits to reduce inhalation of harmful substances.
