What are the causes of lung cancer? 3 causes of lung cancer you must know

Lung cancer is the most common type of cancer, and many people get lung cancer every year. Some people get lung cancer because of long-term smoking, and some get lung cancer because of air pollution. Maybe you don't know much about these causes. So, let's introduce to you in detail what are the causes of lung cancer?

1. Cigarettes release carcinogens when burning. Long-term smokers will be damaged by the substances in the cigarettes, causing proliferation of their own bronchial mucosal epithelial cells. If squamous cell hyperplasia occurs, it will cause squamous cell carcinoma or undifferentiated small cell carcinoma. Some patients who do not have the habit of smoking may also develop lung cancer, but adenocarcinoma is more common.

2. Certain occupations can also be a risk factor for lung cancer, mainly because the nature of the occupation often exposes patients to radioactive substances such as radium, or to some derivatives of such substances. Certain hydrocarbons are also carcinogens, such as mustard gas, coal tar, copper, asbestos, tin, petroleum, asphalt, etc. These patients affected by their occupations often develop undifferentiated small cell carcinoma and squamous cell carcinoma.

3. Certain chronic lung diseases are also common causes of lung cancer. For example, patients with pneumoconiosis, tuberculosis, silicosis and other diseases are more likely to develop lung cancer, and these diseases may coexist with lung cancer. If squamous metaplasia or hyperplasia occurs during the healing process of lung fibrous scars and chronic inflammation of the lungs and bronchi, cancer may develop.

Lung cancer is very harmful to patients. In order to avoid lung cancer, you need to pay attention to the cause of lung cancer. The above is a detailed introduction to the pathogenic factors of lung cancer. After knowing the cause of lung cancer, you can better prevent the occurrence of lung cancer. I hope everyone can stay away from lung cancer.
