Is laryngeal cancer contagious?

Laryngeal cancer is a type of squamous cell carcinoma. It is not an infectious disease and is not contagious. However, among various otolaryngology diseases, laryngeal cancer is a relatively serious one. The incidence of this disease is very high. Therefore, we must prevent laryngeal cancer in our daily lives and actively understand the causes of laryngeal cancer. See the following introduction for details.

(1) Smoking is a prominent cause of laryngeal cancer: 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 transformation, which becomes the basis for carcinogenesis.

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

(3) Chronic inflammatory stimulation: such as chronic laryngitis or respiratory tract inflammation, can cause the disease to worsen and then develop into cancer.

(4) Air pollution is also one of the causes of laryngeal cancer: long-term inhalation of harmful gases and industrial dust can easily lead to laryngeal cancer.

(5) Viral infection: Cancer caused by viruses is very harmful and can also affect the next generation, so people should take precautions.

(6) Precancerous lesions are also a cause of laryngeal cancer: repeated attacks of laryngeal keratosis and benign laryngeal tumors may lead to cancer.

(7) Radiation: It is a well-known fact that radiation causes cancer, and Ren En attaches great importance to this factor.

(8) Sex hormones: Hormone-induced laryngeal cancer is also a common cause, and the percentage of estrogen receptor-positive cells is significantly increased.
