Analyzing the four main causes of laryngeal cancer

Like other malignant tumors, the causes of laryngeal cancer are also relatively complicated, which brings certain difficulties to the correct treatment of laryngeal cancer. What are the common causes of laryngeal cancer ? The following is a list of the common causes of laryngeal cancer.

Common causes of laryngeal cancer include:

1. Physical factors: mainly radiation. Radiation has carcinogenic effects and has long been noticed by clinicians. It is considered one of the main causes of laryngeal cancer. Data suggest that patients who have received radiation therapy for other neck diseases are more likely to develop laryngeal cancer than those who have not received radiation. The latent period of laryngeal cancer after receiving radiation ranges from 5 to 50 years.

2. Chronic stimulation: From the original site of laryngeal cancer, it is easy to occur in the most obvious part of the vocal cord activity friction. Therefore, it is speculated that the cause 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. Clinical statistics show that more than 90% of laryngeal cancer patients are long-term smokers and smokers, and the probability of occurrence is positively correlated with the time and amount of smoking. Smokers and drinkers are at greater risk of developing the disease. Experiments have shown that when normal mucosal epithelium is often and repeatedly subjected to inflammatory stimulation, cells proliferate actively and atypically. At this time, the cytoplasm contains more RNA. The proliferation of cancer cells is actually the active replication of chromosome DNA and the synthesis of cancer proteases. This is also a common cause of laryngeal cancer.

3. Air pollution: According to literature, 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 cause of laryngeal cancer.

4. Malignant transformation of benign laryngeal diseases: Benign diseases of the larynx, such as laryngeal keratosis and laryngeal papilloma, can cause malignant transformation if not treated in time or if repeated surgeries are inappropriate. Literature sometimes suggests that about 5% of laryngeal cancer patients develop from benign diseases. This is also a cause of laryngeal cancer.

The above is an introduction to the common causes of laryngeal cancer. I hope it will be helpful to you. For more questions about the causes of laryngeal cancer, you can consult our online experts, who will answer them in detail.
