What are the causes of throat cancer

Pharyngeal tumors are also called laryngeal cancer. The appearance of pharyngeal tumors can cause hoarseness and difficulty swallowing, and is more common in middle-aged and elderly men. It can occur at all ages, but children and adults have different characteristics of laryngeal papilloma. Children's laryngeal papilloma mostly occurs in children, may be caused by viral infection, and often occurs in multiple parts of the laryngeal mucosa. In addition, long-term inhalation of harmful substances, alcoholism, environmental pollution, laryngeal papilloma or laryngeal mucosal leukoplakia, etc. may be related to the occurrence of laryngeal cancer.

The main causes of throat cancer are:

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

(2) Chronic inflammation: irritation such as chronic laryngitis or respiratory inflammation

(3) Smoking: Tobacco burning produces tobacco tar, of which benzopyrene is carcinogenic. Tobacco smoke can stop or slow the movement of cilia, causing mucosal edema and bleeding, and causing epithelial hyperplasia, thickening, and squamous metaplasia, which is the basis for carcinogenesis.

(4) Air pollution: Long-term inhalation of harmful gases such as sulfur dioxide and industrial dust such as chromium and arsenic can easily lead to laryngeal cancer.

(5) Viral infection is closely related to the occurrence of cancer. It is generally believed that viruses can change the nature of cells and cause abnormal division; 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.

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

(8) Sex hormones: Relevant experiments have shown that the percentage of estrogen receptor-positive cells in laryngeal cancer patients is significantly increased.

The above is an introduction to laryngeal cancer. I believe everyone has a certain understanding of laryngeal cancer. Finally, I wish you all good health.
