What are the causes of laryngeal cancer?

Laryngeal cancer is the third most common malignant tumor and the most common in otolaryngology. Correctly understanding the causes of laryngeal cancer is conducive to the prevention of laryngeal cancer. So what are the causes of laryngeal cancer ? Let's take a look at them together.

The main causes of laryngeal cancer are as follows:

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

2. Air pollution: Long-term inhalation of harmful gases such as sulfur dioxide and industrial dust such as chromium and arsenic can easily cause laryngeal cancer.

3. Smoking: The burning of tobacco can produce tobacco tar, of which benzopyrene can cause cancer. Tobacco smoke can stop or slow the movement of cilia, and also cause mucosal edema and bleeding, causing epithelial hyperplasia, thickening and squamous metaplasia, which becomes the basis for cancer.

4. Chronic inflammatory stimulation: such as chronic laryngitis or respiratory tract inflammation.

5. Viral infection: closely related to the occurrence of cancer. It is generally believed that viruses can cause cells to change their nature and divide abnormally. Viruses can attach to genes and be passed on to the next generation of cells, causing cancer.

6. Precancerous lesions: Laryngeal keratosis and benign laryngeal tumors such as laryngeal papilloma may become cancerous if they recur repeatedly.

7. Radiation: Using radiation to treat neck tumors can cause cancer.
