Throat cancer can cause a person to lose his or her voice in minor cases or endanger his or her life in serious cases. In recent years, the incidence of laryngeal cancer is increasing, and the incidence of laryngeal cancer among young people is on the rise. Some people have lost their larynx due to laryngeal cancer and become halfway mute, the pain of which is unimaginable to an outsider. Early symptoms of laryngeal cancer are usually less obvious, some of them only show hoarseness and foreign body sensation in the throat, which can be easily mistaken as respiratory diseases such as cold, pharyngitis and bronchitis. The causes of pharyngeal cancer are still not very clear, and may be related to long-term excessive smoking, alcohol abuse, stimulation by harmful chemical gases, as well as chronic inflammation, viral infection, radiation and so on. Although cancer is not as terrible as we think, it is better to start with prevention instead of treating the disease after getting it. We should pay attention to some habits in our daily life to reduce the chance of causing cancer and prevent it before it happens. According to the known causes and triggers, the following methods are recommended to prevent laryngeal cancer: 1. Smoking directly damages organs and forms laryngeal cancer. The longer the age of smoking, the higher the incidence rate. Nicotine, coal tar and benzo(a)pyrene in cigarette are carcinogens. 2.No alcohol abuse. Drinking a lot of alcohol for a long time makes the throat congested and edematous, and leads to malnutrition and low immune function, which lays the foundation for the formation of cancer. 3.Stay away from chemical carcinogenic substances. Chemical carcinogens related to laryngeal cancer include sulfur dioxide, chromium, arsenic and so on. Environmental air pollution of living and production, inhalation of the above mentioned harmful gases and dusts will damage the throat and must be well protected. 4.Prevent the harm of bad dietary habits. Some people do not distinguish between winter and summer, three friends often eat hot pot together, spicy hot stimulation constantly, but also non-stop smoking, drinking, not only to the throat, but also to the eyes, trachea, lungs, esophagus, stomach, etc. are harmful, both cause disease, but also deteriorate to form cancer. 5.Be aware of protection when exposed to radiation. Radiation is a cancer-causing factor, and we should be alert to radioactive contamination. We should protect ourselves from damage when examining or treating the neck for many times or in large doses, otherwise we will create conditions for the formation of throat cancer. In addition to the above, it is also necessary to continuously improve body immune function, develop good hygiene habits, pay attention to oral hygiene and prevent respiratory diseases to avoid viral and bacterial infections; eat more fresh vegetables and fruits, some studies have confirmed that the vitamin c and carotene contained in them can reduce the incidence of throat cancer; adhere to physical exercise and maintain a good state of mind can also prevent the occurrence of throat cancer. In conclusion, laryngeal cancer is not terrible and cancer is not equal to death, it is completely curable as long as early treatment is done. Don’t worry, as long as you have a good lifestyle, you will stay away from diseases and reap health.
