summary

Small cell undifferentiated carcinoma (referred to as small cell carcinoma) is one of the most malignant lung cancer, so the patient's diet should be reasonable. Do not overeat, about 1 / 5 of primary lung cancer. Most of the patients were 40-50 years old and had a history of smoking. It often occurs in the large bronchus near the hilar, tends to grow in the submucosa, often invades the extravascular lung parenchyma, and is easy to fuse with the hilar and mediastinal lymph nodes to form a mass. What is the cause of small cell lung cancer? Let's go.

What is the cause of small cell lung cancer?

First, a large number of smoking data show that lung cancer is closely related to smoking. The incidence rate of lung cancer is 10 times higher than that of non-smokers. The higher the amount of smoking is, the higher the probability.

Second: the incidence rate of air pollution in lung cancer city is higher than that in rural area, and the industrial area is higher than residential area. This is mainly related to pollution of the atmosphere such as benzopyrene and other carcinogens produced by industry, transportation, petroleum, coal and gas.

Third: occupational factors long-term exposure to radium, uranium and other radioactive substances, carcinogenic compounds, arsenic, chromium, tin, nickel, coal tar, petroleum mustard gas, asbestos, asphalt, copper and other substances can induce lung cancer.

matters needing attention

Clinical data show that 80% of the diagnosed lung cancer patients smoke more than 20 cigarettes a day for more than 30 years. Quitting smoking can not only protect oneself from the harm of lung disease, but also reduce environmental pollution and reduce the chance of second-hand smoke inhalation.
