What factors are related to laryngeal cancer

Laryngeal cancer is one of the common malignant tumors of the head and neck. The main clinical manifestations of laryngeal cancer are hoarseness, which is progressive, foreign body sensation in the throat, discomfort when swallowing, pain when swallowing, or accompanied by irritating cough, blood in sputum, and in severe cases, difficulty breathing and neck mass.

The following are its triggering factors:

1. Chronic stimulation: From the original location of laryngeal cancer, it is easy to occur in the most obvious part of the vocal cords. Therefore, it is speculated that the occurrence of laryngeal cancer may be related to long-term friction and chronic inflammatory stimulation. Among various chronic inflammatory stimulation factors, tobacco and alcohol stimulation are the most important.

2. Air pollution: According to literature records, workers who have been engaged in wood processing for a long time or are frequently exposed to dust have an increased chance of developing laryngeal cancer. It is believed that asbestos dust has a direct relationship with the occurrence of laryngeal cancer.

3. Malignant transformation of benign laryngeal diseases: Benign diseases of the larynx, such as laryngeal keratosis and laryngeal papilloma, can be transformed into malignant ones if not treated in time or if they are subjected to repeated inappropriate surgical stimulation. Some literature suggests that approximately 5% of laryngeal cancer patients develop from benign diseases.

4. Physical factors: mainly refers to radiation. Radiation has carcinogenic effects and has long been noticed by clinicians. It is considered one of the inducing factors of other malignant tumors, including laryngeal cancer. Data suggest that patients who have received radiotherapy for other neck diseases are more likely to develop laryngeal cancer than those who have not received radiation. The incubation period of laryngeal cancer after receiving radiation varies from 5 to 50 years.
