What are the causes of small cell lung cancer

Small cell lung cancer is a disease with a high morbidity and mortality rate, which seriously damages the health of patients. Many patients with small cell lung cancer do not know the cause of their illness, which is very unfavorable for people to prevent small cell lung cancer. So many people wonder how this disease is caused? Let's take a look at the causes of small cell lung cancer.

Human endogenous factors such as family heredity, reduced immune function, metabolic activity, endocrine dysfunction, etc. may also play a certain role in promoting the incidence of small cell lung cancer.

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

Smoking According to a large number of survey data from various countries, the cause of small cell lung cancer is closely related to smoking. The increase in the incidence of small cell lung cancer is parallel to the increase in cigarette sales. Cigarettes contain many carcinogens such as benzopyrene. The incidence of small cell lung cancer in smokers is 10 times higher than that of non-smokers, and the incidence is high in those who smoke a lot, which is 20 times higher than that of non-smokers.

In daily life, stay away from second-hand smoke pollution, try to avoid outdoor air pollution and kitchen fumes. Choose environmentally friendly decoration materials. Eat a balanced diet, eat more grains, vegetables and fruits. Maintain an optimistic and positive attitude towards life and improve psychological adaptability. Long-term smokers over 40 years old, smokers for more than 20 years, smokers under 20 years old who start smoking more than 20 cigarettes a day, those who are often exposed to coal smoke, coal tar and oil smoke, those who are exposed to excessive radiation, miners, etc., chronic cough, blood in sputum and those with a family history of lung cancer. It is best for high-risk groups to have regular comprehensive physical examinations every year, and CT examinations if conditions permit. If you have irritating coughs, bloody sputum, fire, hemoptysis and other symptoms, you should go to the hospital for treatment in time. Lung cancer patients should follow the doctor's advice and go to the hospital for follow-up examinations on schedule.
