In recent years, as smoking and environmental factors, particularly the countries of the world industrialized countries, lung cancer incidence and mortality are rising rapidly, died of cancer in male patients with lung cancer have been on top of the list.

Lung cancer causes of the top five:

(A) a large number of smokers according to survey information on the cause of lung cancer and cigarette smoking are closely related. The incidence of lung cancer growth and increase in cigarette sales was parallel relationship. Cigarettes contain carcinogens such as benzopyrene. Experimental animals inhalers or smear tar cigarette smoke can trigger respiratory and skin cancer. Smoking habits were the incidence of lung cancer than non-smokers 10 times, a large quantity of smoking were higher incidence than non-smokers 20 times higher. Female patients of lung cancer incidence has increased significantly. Clinical diagnosis of lung cancer cases, cigarette smoking 20 cigarettes a day for more than 30 years or more, accounting for about 80%. In the past 20 to 30 years, China’s smoking is very serious, nearly 3 billion people are smokers, male adult smoking rate by nearly 50%, nearly 5% of women, young smokers and there are many, if not To take the necessary measures to control and discourage smoking, over the next 10 to 30 years the incidence of lung cancer in China is bound to grow further. Long-term smoking can lead to bronchial epithelial cells, P-like epithelial Health, induced differentiation of squamous cell carcinoma or small cell carcinoma. No smoking habit, though may also be suffering from lung cancer, adenocarcinoma, but more common.

(B) of industrial air pollution in developed countries with a high incidence of lung cancer in urban than in rural areas, factories and mines than in areas of high residential area, mainly due to traffic and industrial areas, oil, coal and internal combustion engines, such as post-combustion and dust arising from the asphalt road Benzopyrene contain harmful substances such as cancer-causing hydrocarbon pollution in the atmosphere about. Survey information on the atmosphere in areas of high concentration of benzopyrene, the incidence of lung cancer is also increased. Air pollution and cigarette smoking on lung cancer incidence could promote each other, the synergy effect.

(C) career, has been recognized long-term exposure to uranium, radium, and other radioactive material and its derivatives, carcinogenic hydrocarbons, arsenic, chromium, nickel, copper, tin, iron, coal tar, asphalt, oil, asbestos, Material such as mustard gas, could induce lung cancer, mainly undifferentiated squamous cell carcinoma and small cell carcinoma.

(D) of chronic lung diseases such as tuberculosis, silicosis, pneumoconiosis and lung cancer, and so can co-exist. These cases of cancer incidence is higher than normal. In addition, as well as chronic inflammation of bronchial pulmonary lung disease fiber scar in the healing process may cause hyperplasia or squamous metaplasia, and on this basis that some cases may develop into cancer.

(E) of the human family, internal factors such as genetic, as well as lower immune function, metabolism, endocrine dysfunction, and so may the incidence of lung cancer on a certain role.
