What causes laryngeal cancer

At present, the cause of laryngeal cancer is still difficult to determine, but it is related to the following factors: 1. Excessive drinking: long-term stimulation of the mucous membrane can cause it to degenerate and cause cancer. 2. Radiation: using radiation to treat neck tumors can cause cancer. 3. Chronic inflammation: stimulation such as chronic laryngitis or respiratory tract inflammation. 4. The cause of laryngeal cancer is also related to air pollution: long-term inhalation of harmful gases such as sulfur dioxide and productive industrial dust such as chromium and arsenic can easily cause laryngeal cancer. 5. Precancerous lesions: repeated attacks of laryngeal keratosis and benign laryngeal tumors such as laryngeal papilloma can cause cancer. 6. Sex hormones: relevant experiments have shown that the percentage of estrogen receptor-positive cells in laryngeal cancer patients is significantly increased. 7. 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 transmitted to the next generation of cells to cause cancer. 8. Smoking: tobacco burning can produce tobacco tar, of which benzopyrene can cause cancer, and tobacco smoke can stop or slow the movement of cilia, also causing mucosal edema and bleeding, and making the epithelium proliferate, thicken and squamous, which becomes the basis for cancer.

Laryngeal cancer is divided into primary and secondary types. Primary laryngeal cancer refers to tumors that originate in the larynx, with squamous cell carcinoma being the most common. Secondary laryngeal cancer refers to malignant tumors from other parts of the body that metastasize to the larynx, which is relatively rare. The main symptoms of laryngeal cancer are hoarseness, dyspnea, cough, dysphagia, cervical lymph node metastasis, etc. People at high risk should pay attention to quitting smoking, drinking moderately, and taking preventive measures. Early detection and early diagnosis and treatment are very important for reducing the harm of laryngeal cancer. On the one hand, it can improve the patient's survival rate after surgery, and on the other hand, it is possible to preserve the pronunciation function of the larynx as much as possible and reduce postoperative complications.

The 5-year survival rate of early laryngeal cancer after proper treatment is higher than 90%. Recurrence and metastasis are the main factors affecting prognosis. The more metastatic lymph nodes there are and the larger their size, the lower the 5-year survival rate. The lower the degree of tumor differentiation, the higher the incidence of metastasis. 1. No smoking, and control drinking appropriately. 2. Strengthen environmental awareness and control environmental pollution. 3. Early detection and early treatment. For those who have hoarseness for more than 2 weeks and have a foreign body sensation, a laryngeal examination should be performed in time.
