What are the causes of laryngeal cancer?

Laryngeal cancer (carcinoma oflarynx) accounts for about 1-5% of all tumors in the body. It ranks third in the field of otolaryngology after nasopharyngeal cancer and nasal sinus cancer. The most common age is 50-70 years old. Laryngeal cancer is a relatively common malignant tumor. Its cause is not very clear, but almost all patients have a long history of smoking. Male patients are about 10 times more likely to be female. The highest incidence in China is in Northeast China, North China and East China.

Causes of Laryngeal Cancer

There is no clear cause, but it may be related to the following factors:

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

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

(3) Chronic inflammatory irritation such as chronic laryngitis or respiratory tract inflammation

(4) Air pollution: Long-term inhalation of harmful gases such as sulfur oxides 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 cause cells to change their nature 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: Experiments have shown that the percentage of estrogen receptor-positive cells in laryngeal cancer patients is significantly increased.

The above is a brief introduction to "What are the causes of laryngeal cancer?" For people who are related to the pathogenic factors of laryngeal cancer, it is recommended to take preventive measures for laryngeal cancer and receive specific treatment according to the doctor's instructions. I hope that patients can recover soon! If you have other questions about laryngeal cancer, please consult our experts online or call for consultation.
