What causes small cell lung cancer

Nowadays, the incidence of small cell lung cancer is getting higher and higher, which causes people's physical condition to become worse and worse, making people's lives unhappy. What exactly is caused by small cell lung cancer? Let us learn about what causes small cell lung cancer.

Chronic lung diseases: such as tuberculosis, silicosis, and pneumoconiosis can coexist with lung cancer. The incidence of these lung cancers is higher than that of normal people. In addition, chronic inflammation of the lung bronchus and lung fibrosis scar lesions may cause squamous metaplasia or hyperplasia during the healing process. On this basis, some lung cancer patients may develop into cancer.

Urban pollution: Epidemiological surveys show that the higher the degree of industrialization and modernization in a city, the higher the incidence of lung cancer. Moreover, nowadays, more and more farmland is being developed into high-rise buildings, with fewer and fewer green fields and more and more gray buildings. The pollution that originally belonged to the city is gradually spreading to the countryside, which is even more dangerous.

Fumes: Surveys have found that young and middle-aged women who are exposed to high-temperature fumes while cooking in the kitchen for a long time will increase their risk of lung cancer by 2-3 times. Therefore, female friends must pay attention to the cleanliness and ventilation of the kitchen, reduce high-temperature frying, and don't be too superstitious about range hoods. Smoking is also a common cause of small cell lung cancer.

Smoking: According to a large number of survey data from various countries, the cause of lung cancer is closely related to smoking. The increase in the incidence of lung cancer is parallel to the increase in cigarette sales. Cigarettes contain a variety of carcinogens such as benzopyrene. Experimental animals that inhale cigarette smoke or apply tar can induce respiratory and skin cancer. The incidence of lung cancer in smokers is 10 times higher than that of non-smokers. The incidence of lung cancer in heavy smokers is even higher, 20 times higher than that of non-smokers.
