What causes throat cancer

Laryngeal cancer is mainly caused by genetic factors, environmental factors such as smoking and alcoholism, viral infections such as HPV infection, occupational exposure such as long-term exposure to chemicals, and other physiological factors. In order to prevent and control laryngeal cancer, it is essential to reduce carcinogenic factors in the environment, do early screening and live a healthy lifestyle.

1. Influence of genetic factors

There is a certain family genetic tendency for laryngeal cancer. If there is a history of cancer in the family, it may be more likely to develop laryngeal cancer. This may be related to related gene mutations, but heredity is only one of many risk factors. People with a family history of cancer need to pay more attention to throat health and regularly screen the throat area.

2. The role of environmental factors

Smoking is the primary risk factor for laryngeal cancer. Long-term smoking will cause continuous irritation and damage to the throat mucosa, increasing the risk of cell cancer. Alcoholism and smoking will have a cumulative effect, further increasing the burden on the throat mucosa. People who are exposed to chemicals such as asbestos, soot, and gasoline for a long time are also at high risk of occupational diseases and must take protective measures, such as wearing masks and conducting health monitoring.

3. Links to viral infections

Human papillomavirus (HPV) infection is also closely related to the occurrence of throat cancer, especially HPV16. It can be transmitted to the throat area through oral contact, causing abnormal proliferation of local cells and even cancer. This also makes the importance of preventive HPV vaccination increasingly prominent.

4. Physiological and disease factors

Long-term unhealthy use of the vocal cords, such as frequent loud shouting and repeated throat injuries, may also lead to precancerous lesions. Certain chronic diseases such as chronic pharyngitis may also increase the risk of laryngeal cancer if they are not effectively controlled for a long time. If symptoms such as persistent pain, foreign body sensation and hoarseness occur in the throat, medical diagnosis should be sought as soon as possible to prevent delays in treatment.

5. Influence of lifestyle

Unhealthy eating habits, such as a preference for spicy or overly hot food, long-term physical fatigue or poor work and rest schedule, can weaken the immune barrier of the throat and lay the hidden dangers for cancer. It is recommended to maintain a balanced diet, consume more fruits and vegetables with antioxidant effects, and reduce the frequency of high-temperature and spicy food intake. Quitting smoking and drinking is also very important.

The World Health Organization recommends actively preventing the occurrence of tumors. For throat cancer, developing good living habits, regular screening, and avoiding exposure to high-risk environments can effectively reduce the probability of disease. If you experience throat discomfort, please consult a professional doctor as soon as possible and undergo examination so that targeted treatment measures can be taken.
