How to effectively prevent lung cancer To prevent lung cancer, you need to stay away from five kinds of qi

The incidence of lung cancer is getting higher and higher. It has a serious impact on our body. Each of us should pay attention to prevention. So, what are the hazards of lung cancer? How to effectively prevent lung cancer?

Lung cancer is a serious health hazard

Lung cancer is very harmful to our health. First, the cancerous mass stimulates the nerves in the bronchus, causing severe dry coughs and sometimes coughing up blood. Secondly, our bronchi are blocked by tumors, and the original normal alveolar cysts no longer exist. If lung cancer spreads to the pleura, it can cause chest pain, pleural effusion, and compression of the lungs, which can aggravate breathing difficulties. If lung cancer develops and occupies most of the lungs, it will seriously affect the respiratory function of the lungs. Furthermore, the metabolites of cancer are different from those of normal tissues and have certain toxicity. Therefore, if the tumor is too large, it can endanger life even if it does not invade other organs of the human body. If lung cancer spreads throughout the body and spreads to important organs of the human body such as the brain or liver, it can cause functional disorders of the brain and liver. If the important organs of the human body are damaged too much, it will be difficult to maintain a normal life, and even endanger life. If it is transferred to the bones, it can cause severe bone pain and pathological fractures.

Stay away from the five qi to prevent lung cancer

1. Outdoor air pollution

With the increase of haze weather in recent years, more people are familiar with the term pM2.5. The nasal hair in our nasal cavity can block particles of pM50, and the cilia in the trachea and bronchial cavity can block particles of pM10, but pM2.5 can go straight through the bronchi and bronchioles into the alveolar tissue, and carry harmful substances or carcinogens in the atmosphere into the blood. According to the results of Beijing's air quality test in 2013, the air quality compliance rate last year was 48%, and the primary pollutant pM2.5 accounted for 77.8% of the days exceeding the standard. Severely polluted weather accounts for 16% of the days throughout the year, and the primary pollutant is all pM2.5. Long-term exposure to such air pollution and haze weather will definitely have a significant impact on the incidence of lung cancer.

2. Indoor tobacco smoke pollution

Environmental protection departments and disease control experts have concluded that outdoor air pollution will have a 30% impact on indoor air. For example, if the outdoor pM2.5 is 100, the indoor pM2.5 is 30, but the premise is that there is no indoor pollution. However, indoor air cannot be purified. If you don't pay attention to it, the indoor air will be dirtier than the outdoor air. Among them, tobacco smoke pollution is the largest source of indoor air pollution.

China's tobacco industry has many "world firsts" that make people "howl": the largest tobacco leaf planting area, the largest tobacco leaf purchase volume, the largest cigarette production, the largest cigarette consumption, the largest tobacco profit and tax, the largest number of smokers, and the largest number of people who died from smoking-related diseases. There are thousands of chemical substances and hundreds of harmful substances in tobacco, and 69 carcinogens, which not only cause lung cancer, but also have a great impact on other malignant tumors, cardiovascular diseases, respiratory diseases, digestive diseases, and reproductive diseases. With the increase of age and the extension of smoking years, the balance of oncogenes and tumor suppressor genes in the body changes, and the probability of cancer increases accordingly. Just like arm wrestling, when we are young and strong, we will suppress the other party. When we are old and weak, the other party will suppress us. With the accumulation of harmful substances in tobacco, smokers' resistance gradually decreases, and they will eventually lose and develop cancer. It is worth emphasizing that there is a dose-effect relationship between smoking and the occurrence of lung cancer: if you smoke more than 25 cigarettes a day, the incidence of lung cancer is 227/100,000; if you smoke 15 to 24 cigarettes a day, it is 139/100,000; and if you smoke 1 to 14 cigarettes a day, it is 75/100,000.

Most of the carcinogens in tobacco smoke will spread into the air. These smoke particles are basically smaller than pM0.5, and the harm is much higher than pM2.5. Long-term exposure to secondhand smoke is equivalent to the damage caused by light smoking, which can increase the incidence of lung cancer by 20%~30%. Smoking indoors will also cause pM2.5 to rise sharply or even exceed the limit. In addition, thirdhand smoke has little effect on healthy adults, but it has a great impact on patients with respiratory diseases, infants and the elderly. In particular, young smoking fathers, after smoking, hold their children, and their clothes, skin and hair are covered with thirdhand smoke, which will also cause harm to the health of infants and young children.

Therefore, for the sake of their own health and the health of those around them, smokers should quit smoking as soon as possible; even if they smoke, they should not smoke indoors or in the car; non-smokers should also dare to say "no" to smokers and suggest that smokers go outdoors to smoke.

3. Kitchen fume pollution

Kitchen fumes are the second largest factor in indoor air pollution. Fuel, kitchen utensils, cooking oil usage, cooking methods, installation, use and maintenance of range hoods are very important in reducing kitchen fume pollution. For example, a small amount of smoke will appear when cooking oil is heated to 170°C, and a large amount of fumes will appear at 250°C. When frying, deep-frying, stir-frying and grilling, the oil temperature will be above 260°C. Benzopyrene and volatile nitrosamines produced by cooking fumes are extremely harmful to human health. The greater the cooking fume and the longer the exposure time, the greater the risk of lung adenocarcinoma.

Therefore, in order to reduce kitchen fume pollution, you should pay attention to keeping the kitchen ventilated, put more green plants, barbecue less at home, and scientifically purchase, install, use and maintain the range hood. Many people always wait until the oil pan smokes before turning on the range hood when cooking, and turn it off immediately after cooking. If you save 8 cents a day on electricity, you can save more than 600 yuan by cooking for so many years, but if you get lung cancer, it will cost at least 60,000 yuan. In addition, if the kitchen fume is not discharged in time, it will drift to the living room and bedroom, deposited on the curtains and furniture, and it is difficult to remove.

4. Air pollution caused by decoration materials

The stones used in decoration, especially marble, contain radon, which is a type of carcinogen. Long-term exposure to radon pollution can cause blood cancer and lung cancer. It is recommended to minimize the use of stone materials, or choose green stone materials recognized by the environmental protection department. Various paints and adhesives contain a large amount of benzene and formaldehyde, which are also an important part of indoor air pollution. Therefore, it is recommended to focus on decoration and light decoration during decoration, use less chemical adhesives for floor leather, and decorate the walls with calligraphy and paintings. After decoration, it is necessary to ventilate for a period of time before living; in northern regions, it is recommended to use air purifiers and air humidifiers, the former for pM2.5, and the latter for pM10, which helps to improve indoor air quality. In addition, placing more green plants or activated carbon in the room can also help absorb pollution particles.

5. Sulking

I call sulking "psychological pollution" and this kind of personality "cancer personality". When negative events occur in life or work, such as the death of a spouse or a loved one, people with this kind of cancer personality will not be able to adjust their mentality for a long time and are not good at communicating with relatives and friends, which will cause a great negative impact. Therefore, when you are depressed, you must communicate more with your family and friends to resolve your emotions and reduce psychological pollution as much as possible. People with withdrawn personalities should learn to adjust themselves and seek help from a psychologist when necessary to face negative events correctly.
