Lung cancer is the only cancer that is increasing worldwide. What causes the high incidence of lung cancer? Air pollution and smoking are important factors. Non-smokers who are exposed to pollution sources for a long time or even get angry frequently will harm the health of their lungs and become the cause of lung cancer. Lung cancer is a primary epithelial malignant tumor that grows in the trachea, bronchi and lungs. The early symptoms are not obvious, and most patients are already in the late stage when discovered. Once diagnosed, the long-term survival rate is lower than other cancers. Therefore, in life, we should be careful to stay away from the following four kinds of "qi". Smoke Smoking is one of the main causes of lung cancer. Male smokers are 10 times more likely to get lung cancer than non-smokers, and female smokers are 5 times more likely to get lung cancer. Heavy smokers have a higher incidence of lung cancer. Cigarettes contain a variety of carcinogens such as benzopyrene. Experimental animals that inhale cigarette smoke or apply tar may develop respiratory and skin cancer. More than 85% of lung cancer deaths are related to smoking. atmosphere Air pollution and environmental pollution are also important reasons for the high incidence of lung cancer. Areas where PM2.5 seriously exceeds the standard are even more serious than tobacco, because PM2.5 can be directly inhaled into the alveoli, stay in the alveoli, and even enter the blood through the alveoli. In industrially and transport-developed areas, the atmosphere is polluted by harmful substances such as benzopyrene, a carcinogenic hydrocarbon, produced by the combustion of petroleum, coal and internal combustion engines, as well as asphalt and road dust, which increases the incidence of lung cancer among people in these areas. Indoor air Indoor air includes second-hand smoke, decoration pollution, kitchen fume pollution and gas. 25% of non-smokers get lung cancer from inhaling secondhand smoke. The chance of getting lung cancer from long-term exposure to secondhand smoke is about twice that of non-smokers. The pollution from cooking fumes and burning incense in religious customs also makes Oriental women more likely to develop lung adenocarcinoma than those in Western countries. angry People who are often angry and in a bad mood will cause great damage to their bodies and have a greater chance of developing cancer. When you are angry, your emotions become impulsive, your breathing becomes rapid, and you may even hyperventilate. The alveoli continue to expand and have no time to contract, so you cannot get the proper relaxation and rest, which is very harmful to the health of your lungs. Being angry will not cause cancer, but it is a cause of cancer. When you are angry, take some deep breaths to give your alveoli a rest. |
