1 causes of high incidence of lung cancer in women.
The national survey of cancer mortality from 1973 to 1975 found that the lung cancer mortality rate of women in Xuanwei County, Yunnan Province was the highest in the country, which was more than 4 times higher than that of American women in the same period. In order to explore the causes of the high incidence of lung cancer among women in Xuanwei County, in order to take effective strategies and intervention measures to reduce the harm and burden of lung cancer, the former Institute of Health of the Chinese Academy of Preventive Medicine cooperated with the local health and epidemic prevention and tumor prevention departments. a large number of epidemiological investigations and etiological studies were carried out in Xuanwei County, which proved that indoor coal-fired air pollution was the main decisive factor. It is an economically feasible control intervention. A large number of experiments and research results show that compared with the non-furnace change group, the indoor air quality of residents is significantly improved and the concentration of carcinogens is significantly reduced, which can reduce the mutagenicity caused by indoor coal combustion pollution by 96.7% to 97.7%. By changing the stove for 10 years, the mortality rate of lung cancer can be reduced by 2.9-3.6 times, and the mortality rate of lung cancer can be reduced by 9.7-11.4 times for more than 10 years. The successful experience of Xuanwei demonstration Base for Comprehensive Prevention and treatment of Lung Cancer has been fully affirmed by the World Health Organization and is being promoted all over the world.2 high incidence sites with serious harm and burden of cancer.The progress and experience of our country in establishing a comprehensive prevention and control research demonstration base at the high incidence site of cancer and conducting the comprehensive prevention and control research of common cancer shows that we should select the high incidence site with serious cancer harm and burden, and establish a comprehensive prevention and control demonstration area. rely on the urgent desire and enthusiasm of the local government and people to control cancer, and make full use of the research conditions and resources provided by cancer high-risk groups. Organizing the research on comprehensive prevention and control of cancer and promoting the development of local comprehensive prevention and control of cancer will not only help to reduce the burden of cancer morbidity and death, but also provide a research base for major national scientific and technological research projects. it is helpful to carry out international collaborative research on cancer, explore the way of prevention and control of tumors with Chinese characteristics, and make greater contributions to realizing the dream of the great rejuvenation of the Chinese nation.
