How to prevent laryngeal cancer

The incidence of laryngeal cancer accounts for about 1% to 5% of all tumors in the body, ranking third in the field of otolaryngology, after nasopharyngeal cancer and nasal and paranasal sinus cancer. The most common age is 50 to 70 years old. It is more common in men than in women, about 8:1, with the highest incidence in Northeast China, North China and East China.

Prevention of laryngeal cancer includes

1. First of all, smoking control: tobacco tar is produced when tobacco is burned, and the benzopyrene in it can cause cancer. In addition, the smoke in tobacco can stop or slow the movement of cilia, and can also cause mucosal edema and bleeding, causing epithelial hyperplasia, thickening, and squamous metaplasia, which is the basis for cancer. Smoking ban is the top priority of cancer prevention and treatment.

2. Excessive drinking: Long-term drinking can irritate the mucous membrane and cause it to degenerate and lead to cancer.

3. Cure chronic laryngeal diseases as soon as possible. Chronic inflammation can easily stimulate pathological changes such as chronic laryngitis or respiratory tract inflammation.

4. 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.

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

6. Sex hormones: Relevant experiments show that the percentage of estrogen receptor positive cells in laryngeal cancer patients is significantly increased.

7. Precancerous lesions: Repeated attacks of laryngeal keratosis and benign laryngeal tumors such as laryngeal papilloma may lead to cancer.

8. Reduce air pollution and eliminate occupational hazards. Long-term inhalation of harmful gases in the air such as sulfur dioxide and industrial dust such as chromium and arsenic can easily lead to laryngeal cancer.

Occupational hazards and the resulting cancers are becoming increasingly serious. The production and use of carcinogenic substances should be prohibited and controlled; efforts should be made to replace carcinogenic substances with non-carcinogenic substances or substances with less harm; health supervision and monitoring should be strengthened to control the exposure concentration in the production environment below the legal health standards.
