The incidence of lung cancer is getting higher and higher, each of us should pay attention to prevention. Let’s take a look at the five kinds of gas that we should keep away from to prevent lung cancer. One kind of gas: outdoor air pollution In these years, with the increase of hazy weather, more people are familiar with the term PM2.5. The nasal hairs in our nasal cavity can block PM50 particles, and the cilia in the lumen of trachea and bronchial tubes can block PM10 particles, while PM2.5 can enter the alveolar tissues through the bronchial tubes and fine bronchial tubes and carry harmful substances in the atmosphere or carcinogens into the bloodstream. 2013 air quality test results, last year, the air compliance rate was 48%, and the primary pollutant on the day of exceeding the standard was PM2.5. PM2.5 accounted for 77.8%. Heavily polluted weather accounted for 16% of the annual number of days, and the primary pollutant was all PM2.5. Prolonged exposure to such air pollution and hazy weather will definitely have a significant impact on the development of lung cancer. Second Air: Indoor Tobacco Smoke Pollution Outdoor air pollution will bring about 30% of the impact on indoor air, for example, if the outdoor PM2.5 is 100, indoor is 30, but the premise is that there is zero indoor pollution. However, indoor air cannot be purified, and if not taken seriously, indoor air can be dirtier than outdoor. Among them, tobacco smoke pollution is the number one source of indoor air pollution. China’s tobacco industry has a lot of people “thought howling” of the “world’s first”: the first area of tobacco planting, the first purchase of tobacco, the first cigarette production, the first cigarette consumption, the first tobacco profits and taxes, the first number of smokers, the number of people who died of smoking-related diseases is also the first. The number of smokers and the number of deaths from smoking-related diseases are also the highest. Tobacco has thousands of chemical substances, hundreds of harmful substances, and 69 types of carcinogens, which not only cause lung cancer, but also have a great impact on other malignant tumors, cardiovascular diseases, whooping diseases, digestive diseases, and reproductive diseases. As we get older and smoke longer, the balance of oncogenes and oncogenes in the body changes, and the chance of developing cancer increases. It is just like arm wrestling, when we are young and powerful, we will press the other side, when we are old and weak, the other side will press us, and with the accumulation of harmful substances in tobacco, the resistance of smokers gradually decreases, and they will eventually lose the battle and produce cancer. It is worth emphasizing that there is a dose-effect relationship between smoking and lung cancer: smoking more than 25 cigarettes a day, the incidence of lung cancer is 227/100,000, 15~24 cigarettes is 139/100,000, and 1~14 cigarettes is 75/100,000. Most of the carcinogens in tobacco smoke will diffuse into the air, and these smoke particles are basically smaller than PM0.5, and the harm is much higher than PM2.5. Long-term exposure to secondhand smoke, equivalent to the damage caused by light smoking, can increase the incidence of lung cancer by 20% to 30%. Smoking indoors can also cause PM2.5 to soar or even explode. In addition, third-hand smoke has little effect on healthy adults, but has a great impact on people with whooping disease, infants and the elderly. Especially young smokers, fathers, smoking after holding children, clothing, skin and hair are third-hand smoke, will also bring harm to the health of infants and young children. Therefore, in order to their own health as well as those around them, smokers should quit smoking as soon as possible; even if smoking should not be indoors and in the car; non-smokers should also dare to say “no” to smokers, and proposed to let smokers go outdoors to smoke. Three gas: kitchen fumes pollution Kitchen fumes are the second largest element of indoor air pollution. Fuel, kitchen utensils, cooking oil use, cooking methods, installation and maintenance of range hoods to reduce kitchen fumes pollution have a lot to learn. For example, when cooking oil is heated to 170℃, a small amount of smoke will appear, and at 250℃, a large amount of oil smoke will appear. Frying, deep-frying, stir-frying and barbecue, the oil temperature will be above 260 ℃, cooking process fumes produced by benzo(a)pyrene, volatile nitrosamines, etc. to bring great harm to human health. The greater the cooking fumes, the longer the exposure time, the greater the risk of lung cancer. Therefore, in order to reduce the kitchen smoke pollution, should pay attention to keep the kitchen ventilation, more green plants, less home barbecue, scientific purchase, installation, use and maintenance of range hoods. Many people frying, always wait for the frying pan smoke before turning on the range hood, frying immediately after the food off. According to a day to save 8 cents electricity to calculate, frying for so many years probably can save more than 600 yuan, but if you get lung cancer, at least to spend 60,000 yuan. In addition, if the kitchen fumes are not discharged in time, they will drift to the living room, bedroom, deposited on the curtains and furniture, which is difficult to remove. Fourth gas: air pollution from decoration and decorative materials The stone used in decoration, especially marble has radon element, which belongs to a class of carcinogenic substances, and long-term exposure to radon pollution will lead to blood and lung cancer. It is recommended to minimize the use of stone, or choose green stone materials recognized by the environmental protection department. Various paints and adhesives contain large amounts of benzene and formaldehyde, which are also important components of indoor air pollution. Therefore, it is recommended to decorate the best heavy decoration, light decoration, less use of floor leather chemical adhesive adhesive, the wall can be decorated with paintings. After the renovation must be ventilated for a period of time before living; the northern region is recommended to use air purifiers and air humidifiers, the former for PM2.5, the latter for PM10, to help improve indoor air quality. In addition, more green plants or activated charcoal in the living room will also help adsorb pollution particles. Five gas: Sulking Sulking is always called “psychological pollution”, and this character is called cancer character. When there is a negative event in life or work, such as the loss of a spouse, the death of a loved one, etc., this cancerous character of the person for a long time to adjust the mind, and not good with friends and relatives to communicate, resulting in the negative impact will be great. Therefore, when depressed, we must communicate more with family members and close friends to resolve emotions and minimize psychological pollution. People with withdrawn personality should learn to adjust themselves, ask psychiatrists for help when necessary, and face negative events correctly. Lung Cancer 6 Hazards to Health 1. When the cancerous lumps stimulate the nerves in the bronchial tubes, violent dry cough will occur, and sometimes coughing up blood can happen. 2.Bronchial tubes are blocked by tumors, and the original normal alveolar cystic cavity no longer exists. 3.If the lung cancer extends to the pleura, it may cause chest pain, or there may be pleural fluid, which may aggravate the difficulty in whistling by compressing the lungs. 4.If lung cancer develops and occupies most of the lungs, it will seriously affect the whistling function of the lungs. 5. The metabolites of cancer are different from those of normal tissues and have certain toxicity. Therefore, if the cancer is too big, even if it has not invaded other organs of the human body, it can be as life-threatening as well. 6. If lung cancer spreads to the whole body and spreads to important organs such as brain or liver, it can cause functional disorder of brain and liver, and if the important organs are damaged too much, it will be difficult to maintain a normal life and even jeopardize the life. If it spreads to bones, it can cause severe bone pain and pathological fracture.
