What are the causes of throat cancer

We now live in a polluted environment, so the incidence of many diseases is getting higher and higher. We all hope to be healthy and live happily. However, many patients still suffer from cancer. Laryngeal cancer is a type of cancer. Although the incidence of this cancer is not very high, it also brings great pain to patients. In order to prevent laryngeal cancer, we need to know the causes of this disease. The following article explains the causes of laryngeal cancer. Let's take a look!

Overview of Laryngeal Cancer

Laryngeal cancer (carcinoma oflarynx) is a relatively common malignant tumor, with an incidence rate of about 1% to 5% of all tumors in the body. In the field of otolaryngology, it ranks third after nasopharyngeal carcinoma 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, and the highest incidence rate is in Northeast China, North China and East China. The cause of the disease is not very clear, but the patients almost always have a long history of smoking. Symptoms vary depending on the vocal location of the cancer. Hoarseness may occur in the early stages of vocal cord cancer, while supraglottic cancer often manifests as discomfort in the throat or foreign body freezing, pain, and is often not obvious, which can easily delay diagnosis. In the late stage, obvious hoarseness, laryngeal sound, shortness of breath, difficulty breathing, pain, swallowing disorders, and neck masses and cervical lymphadenopathy may occur.

Causes of Laryngeal Cancer

Generally speaking, the occurrence of laryngeal cancer is closely related to many factors in life. For people who have a long-term habit of excessive drinking, their chance of suffering from laryngeal cancer is much higher than other people. It can be seen that understanding the causes of laryngeal cancer will help people reduce the chance of laryngeal cancer occurring in themselves.

(1) Smoking: Tobacco burning produces tobacco tar, of which benzopyrene can cause cancer. Tobacco smoke can stop or slow the movement of cilia, cause mucosal edema and bleeding, and cause epithelial hyperplasia, thickening, and squamous metaplasia, which become the basis for cancer.

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

(3) Chronic inflammatory irritation such as chronic laryngitis or respiratory tract inflammation,

(4) Air pollution: Long-term inhalation of harmful gases such as sulfur dioxide and industrial dust such as chromium and arsenic can easily lead to laryngeal cancer.

(5) 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.

(6) Precancerous lesions: Laryngeal keratosis and benign laryngeal tumors such as laryngeal papilloma may become cancerous if they recur.

(7) Radiation: Radiation therapy for neck tumors can cause cancer.

(8) Sex hormones: Relevant experiments have shown that the percentage of estrogen receptor-positive cells in laryngeal cancer patients is significantly increased.

The above article explains the causes of laryngeal cancer. The causes of laryngeal cancer are radiation, sex hormones, precancerous lesions, viral infections, air pollution, chronic inflammatory stimulation, smoking and excessive drinking. We must pay attention to the above matters in our daily lives, and also pay attention to diet, adjust our mood, and actively cooperate with the doctor's treatment. Finally, I wish the patient a speedy recovery.
