In the dreaded kingdom of cancer, lung cancer has quietly become the boss. It is the more common malignant tumor worldwide, ranking first in the number of new cases and deaths every year. And its power is expanding, especially in China, where the incidence rate is still climbing. What makes lung cancer the leader? First of all, it is genetic factor, which is certainly not the case, but it does have genetic tendency and there is a certain family gathering phenomenon. Secondly, environmental factors also play a very important role in the development of lung cancer. Many people are exposed to harmful substances for a long time because of their occupations and have a higher risk of getting lung cancer than the general population. For example, workers in thermal power plants are exposed to tar and soot, which can cause lung cancer, for a long time, and if they do not strengthen their occupational protection, the possibility of lung cancer is very high. Cigarette smoke is the most important factor that induces lung cancer, and second-hand smoke and third-hand smoke also increase the risk of lung cancer. The more you smoke, the longer you smoke, the greater your risk of lung cancer. ”If a man doesn’t smoke, he comes to the world in vain,” and anyone who insists on this viewpoint and keeps on swallowing the smoke is simply advocating for lung cancer! In addition to harming yourself, secondhand smoke caused by smoking may also harm your family and friends around you to develop lung cancer. In recent decades, the incidence of lung cancer in men in developed countries in Europe and the United States has shown a declining trend, and the control of tobacco has been instrumental in proving that smoking induces cancer. Polluted atmosphere Atmospheric pollution is another culprit of lung cancer, and its pattern is obvious: the incidence of lung cancer is higher among residents of densely populated large cities than those in rural areas. The more polluted the atmosphere is, the higher the incidence and mortality rate of lung cancer. So, make some demands on the environment you live in. Soot pollution and grease pollution in the kitchen are important reasons for increasing the risk of lung cancer in women. 1. Soot pollution: mainly from households burning honeycomb coal, the carcinogenic substances released by indoor coal burning are many times more than smoking. With the continuous development of urbanization, this type of pollution has been gradually reduced. 2. Oil smoke pollution: When frying or pan-frying food, the oil smoke formed by high-temperature cooking oil contains a large number of carcinogens, such as benzo(a)pyrene. In China, many women cook in the kitchen for a long time and are exposed to soot or high-temperature oil smoke, and their risk of lung cancer is higher than others. We can’t afford to mess with them, but we can avoid them. In general, the above-mentioned gases are the more important risk factors for lung cancer. But the good thing is that they can also be changed through efforts. Decades of practice in Western countries have proved that vigorous tobacco control, management of air pollution and control of indoor air pollution can effectively reduce the incidence and mortality rate of lung cancer. In response to smoking, the best way is to quit smoking, which is beneficial to people and themselves. In response to air pollution, the government needs to vigorously combat pollution. For individuals, the most direct measure is to wear a mask when the air quality is bad. For grease gas, on the one hand to improve cooking methods, minimize frying, frying, frying and other cooking methods, on the other hand, you can choose to improve the cooker, try to select the installation of grease smoke absorption rate is relatively high kitchen appliances, such as integrated cooker.
