What are the main causes of lung cancer? 3 factors are likely to induce lung cancer

The incidence of lung cancer is increasing year by year, seriously affecting people's health. In order to avoid the harm of lung cancer, we need to take effective measures to prevent the disease in time. It will be more effective to prevent the main pathogenic factors of lung cancer. Smoking, kitchen fumes, air pollution, etc. are all major factors that cause lung cancer.

1. Air pollution

Survey data show that the more harmful substances such as benzopyrene carcinogenic hydrocarbons are contained in the atmosphere, the higher the incidence of lung cancer will be. Dust from asphalt roads and combustion of internal combustion engines, coal and oil will produce harmful carcinogens. In areas with developed industries and transportation, air pollution containing carcinogens will be more serious, and the incidence of lung cancer will also be very high.

2. Occupational factors

The main causes of lung cancer also include certain occupational factors. Long-term exposure to radioactive substances such as uranium and radium and their derivatives due to the nature of the work will increase the incidence of lung cancer. Frequent exposure to certain carcinogenic hydrocarbons, mustard gas, coal tar, copper, chromium, petroleum, iron, asbestos and other substances can also easily lead to the occurrence of lung cancer.

3. Chronic lung diseases

If pneumoconiosis, tuberculosis, silicosis, etc. occur, the incidence of lung cancer is higher than that of normal people, and these diseases may coexist with lung cancer. If squamous metaplasia occurs during the healing process of lung fibrosis scar lesions and chronic inflammation of the lung bronchus, some patients may develop lung cancer from these diseases.

Certain chronic lung diseases are also the main risk factors for lung cancer. If people suffer from pneumoconiosis, tuberculosis and silicosis, their chances of developing lung cancer will be higher. Therefore, we must take timely prevention measures to prevent minor illnesses from becoming major ones and major illnesses from becoming terminal ones.
