What are the causes and symptoms of lung cancer?

summary

In recent years, lung cancer is also the main disease that endangers human life. It brings great pain and trouble to human beings. For most patients with early lung cancer, "Pingfei Gujin prescription" can be used for conditioning. Traditional Chinese medicine conditioning can help to inhibit the deterioration of the disease and regulate the health of the lung. Lung cancer is not easy to be found in the early stage, but it is often found in the middle and late stage, which may lose the best opportunity for treatment

What are the causes and symptoms of lung cancer?

Smoking accounts for 80% of lung cancer in men and 79% of lung cancer in women. Nicotine, benzopyrene, nitrosamine and a small amount of polonium in smoke can cause cancer, especially squamous cell carcinoma and small cell carcinoma. Lung cancer can also be induced by cigarette smoke and tar in animal experiments. A retrospective and prospective study designed by the strict design showed that there was a significant dose effect relationship between smoking and lung cancer. The younger the age of smoking, the longer the time of smoking and the higher the amount of smoking, the higher the incidence rate and mortality of lung cancer. Passive smoking or environmental smoking is also one of the causes of lung cancer.

In the industrial production of occupation and lung cancer, the special substances related to lung cancer are asbestos, arsenic, chromium, benzopyrene, coal tar, trichloromethyl ether, heating products of tobacco, radon and radon gas produced by decay of radioactive substances such as uranium and radium, ionizing radiation and microwave radiation. These factors can increase the risk of lung cancer 3-30 times.

Air pollution and lung cancer: the mortality of lung cancer among urban residents is higher than that in rural areas in both the United States and the United Kingdom, and it increases with the degree of urbanization. In the atmosphere of heavy industrial cities, there are carcinogens such as 3,4-benzopyrene, arsenic oxide, radioactive substances and non combustible aliphatic hydrocarbons. In the heavily polluted cities, the daily intake of BaP in the air can exceed 20 cigarettes, and increase the carcinogenic effect of cigarettes. For every 1-6.2% increase in BAP content in the atmosphere μ The mortality of lung cancer can be increased by 1% ～ 15% when the dosage is 1 000 g / 1000m3.

matters needing attention

Avoid spicy food: onion, garlic, leek, ginger, pepper, pepper, cinnamon, avoid fried, barbecue and other hot food; Proper exercise: strengthening exercise, enhancing the body's ability to resist disease and avoiding long-term stimulation of carcinogenic factors can reduce the incidence rate.
