What are the possible causes of laryngeal cancer

The causes of laryngeal cancer are very common in life. If not controlled in time, cancer cells will gradually spread and cause more complications. What are the causes of laryngeal cancer?

1. Excessive drinking: Long-term stimulation of the mucous membrane can cause it to degenerate and cause cancer.

2. Long-term smoking. This is the main cause of laryngeal cancer. The burning of tobacco can produce tobacco tar, of which benzopyrene can cause laryngeal cancer. In addition, the smoke in tobacco can stop or slow the movement of cilia, causing mucosal edema and bleeding in laryngeal cancer patients, causing epithelial hyperplasia, thickening, and squamous metaplasia, which becomes the basis for laryngeal cancer.

3. Air pollution. Long-term inhalation of harmful gases, such as sulfur dioxide, and industrial dust, such as chromium and arsenic, can cause laryngeal cancer. The incidence of laryngeal cancer is high in cities with serious air pollution, and the incidence in urban residents is higher than that in rural residents.

4. Sex hormones. Relevant experiments have shown that the percentage of estrogen receptor positive cells in laryngeal cancer patients is significantly increased. This is also one of the causes of laryngeal cancer.

5. Occupational factors: Long-term exposure to toxic chemicals, such as mustard gas, asbestos, nickel, etc.

6. Viral infection: Human papillomavirus (HPV) can cause laryngeal papilloma, which is currently considered a precancerous lesion of laryngeal cancer.

7. Exposure to radiation. Long-term exposure to radioactive nuclides, such as radium, uranium, and radon, can cause malignant tumors.
