Long-term exposure to radioactive substances such as uranium and radium and their derivatives, carcinogenic hydrocarbons, arsenic, chromium, nickel, copper, tin, iron, coal tar, pitch, petroleum, asbestos, mustard gas and other substances can induce lung cancer, mainly squamous cell carcinoma and undifferentiated small cell carcinoma.
What causes lung cancer?
Many people in life do not know the reason why they suffer from lung cancer, and do not know why they are troubled by lung cancer.
This is because everyone does not know the common sense of lung cancer. Today we will introduce the causes of lung cancer.
1. Smoking: Carcinogens are released when cigarettes burn. Long-term smoking can induce squamous cell carcinoma or undifferentiated small cell carcinoma in the bronchial mucosa. Although non-smokers can also suffer from lung cancer, adenocarcinoma is more common.
2. Air pollution: The air is too polluted.
3. Occupational factors: Long-term exposure to radioactive substances such as uranium and radium and their derivatives can induce lung cancer, mainly squamous cell carcinoma and undifferentiated small cell carcinoma.
4. Chronic lung diseases: Such as tuberculosis, silicosis, pneumoconiosis, etc., which can coexist with lung cancer, have a higher incidence of cancer than normal people. In addition, chronic inflammation of the lungs and bronchi and pulmonary fibrosis scar lesions may cause squamous epithelial metaplasia or hyperplasia during the healing process, and on this basis, some cases may develop into cancer.
5. Internal factors of the human body: such as family inheritance, reduced immune function, metabolic activity, and endocrine dysfunction.
The occurrence of lung cancer is mostly related to long-term smoking and passive smoking, long-term adverse environmental factors and occupational factors. It has a long “latent period”. It takes many years of adverse stimulation to cause tumors. Therefore, the number of patients with lung cancer among the elderly has increased relatively.
Lung cancer patients should pay more attention to the common sense of lung cancer in their lives, which can not only help the treatment of lung cancer, but also reduce the pain of the body. Finally, we wish all patients can get healthy as soon as possible.
