Core Tip: In winter, the weather is cold. Most of the households are closed with doors and windows. It is not known that this will lead to indoor air pollution and increase the chance of illness. It is necessary to know the incidence of airway diseases such as lung cancer and air quality.
Smoke, fume, pollution, indoor air, Beijing Xuanwu Hospital, Department of Thoracic Surgery, Professor Xiuyi, pointed out that China has a map of cancer, especially lung cancer, winter heating in northeast and north China, plus moderate to severe air pollution in some areas, the incidence of lung cancer is relatively High. Taking lung cancer as an example, among the risk factors for lung cancer, smoking and air pollution accounted for 22%, lung and bronchial diseases, occupational factors, and genetic factors accounted for 12%-15%, and mental factors and age accounted for 8% and 5, respectively. %.
He pointed out that the air pollution mentioned above is two concepts, one is air pollution and the other is indoor air pollution. Outdoor air pollution people can hide indoors, indoor air pollution is difficult to hide, such as smoke including second-hand smoke, three-hand smoke, which is also an important factor of PM2.5.
In addition, the ventilation of the kitchen in winter will be reduced, and the kitchen fumes caused by Chinese-style cooking frying will also threaten the indoor air in winter. There are also unreasonable household range hoods. To know that the effective height of the range hood is 90 cm, for the sake of beauty, some families have raised the range hood, which can not fully play a role. Moreover, some households and other oil pans started to smoke, and they opened the range hood. When they finished cooking, they closed and could not effectively remove the fumes.
Ventilation and green plants help clean air experts to remind you to reduce indoor air pollution in winter. In addition to smoking ban, you can plant more green plants indoors, and open windows every day at noon when the temperature is relatively high. At this time, it is necessary to keep warm, and those with weak constitutions such as the elderly and the elderly should change to other rooms.
Experts also reminded that if living in a high-risk area of ​​lung cancer or a high-risk group, if there is a family history of cancer or occupational risk factors, a physical examination should be conducted every year. Low-dose spiral CT should be used for chest cancer without early lung cancer. He Baoming, chief physician of the Third Hospital of the People's Liberation Army General Hospital, pointed out that for lung cancer, in the early diagnosis, PET/CT relatively found tumors about one year earlier than the routine examination, and it was possible to detect tumors of 0.5 mm in size. Early diagnosis of many tumors can lead to valuable treatment time. Experts also warned that if there is irritating cough, blood in the sputum, bloodshot sputum, be alert to lung cancer.
