I believe many people have heard of lung cancer, which is the number one killer nowadays. In fact, lung cancer is completely preventable, so do you know how to prevent lung cancer better? Lung cancer is a disease that is caused by “gas” The trend of lung cancer incidence in the past 10 years shows that the cumulative risk of lung cancer in women has increased by more than 30%, and the proportion of women among stage IV lung cancer patients is larger. Lung cancer is a chronic disease that can be prevented and treated by “gas”. To prevent lung cancer, women should pay close attention to the “three hazes” of outdoor haze, indoor smoke haze and inner haze, and pay attention to regular health checkups for early detection, early diagnosis and early treatment. 64% of deaths due to second-hand smoke are women Indoor air pollution – smoke haze is easier to be ignored by women friends, and should cause widespread concern throughout society. Indoor smoke haze includes tobacco smoke, kitchen fumes, VOC of decorative materials in housing renovation and small environmental pollution such as private cars and offices. The number of people exposed to secondhand smoke in China is 740 million, and more than 100,000 people die from secondhand smoke exposure each year. Eighteen cities have introduced local tobacco control regulations, and Beijing, Shenzhen, and Shanghai have passed and begun implementing comprehensive tobacco control regulations for indoor public places. In cities and regions where legislation is not yet in place, smoking is virtually unrestricted in many indoor public places, and “secondhand smoke” is very common among women. WHO data from 2009 show that 64% of all deaths caused by secondhand smoke are among women. Ways to prevent lung cancer in women 1, ban and control smoking: ban and control smoking, first of all, should focus on reducing the proportion of smokers in the population, need to develop certain laws or regulations to limit people, especially to limit women smoking. 2, choose a good kitchen: kitchen fumes are also the primary cause of lung cancer in women, experts recommend that the kitchen should choose a large space, open design, and try to choose a good smoke extraction hood 3, eat vegetables and fruits: all should eat more fresh vegetables and fruits, fruits and vegetables are rich in vitamin C, which is a cancer inhibiting substance that can block the generation of cancer cells, in addition, garlic also contains anti-cancer substances. 4.Regular medical checkups: All people should learn to protect themselves, and regular medical checkups are an important way of protection. Medical checkups can understand the state of health in advance, so that the condition can be detected and treated early. 5, the choice of hood: buy an efficient range hood. Good is the kind of hood installed very close to the cooking fire source. The standard for effective fume extraction is that you can’t smell the stir-fry at a distance of one meter from the stove. Data from a study in Taiwan showed that not using a venting device in cooking increases the risk of lung cancer by 3.2 to 12.2 times. Cooking on a stove with a poor ventilation system and very low combustion efficiency can cause damage to health equivalent to smoking two packs of cigarettes a day. According to a survey by the World Health Organization, most Chinese women are non-smokers but have a high incidence of lung cancer, which is the reason.
