The etiology and pathology of tongue cancer is still relatively clear, with clear relationships to oral hygiene, excessive alcohol and smoking, nutritional deficiencies, pathogenic microorganisms such as viruses and fungi, and so on. An example is the lack of attention to oral health and hygiene. Oral health and hygiene includes many things, such as maintenance of cleanliness, treatment of dental disease, and so on. In addition, chronic injuries, long-term adverse stimuli, and changes in immunity are associated with the development of tongue cancer, and many of these triggers can be avoided. Another example is chronic injury, many patients think that oral diseases are still minor and do not need to seek medical treatment if they have no symptoms. Some patients do not pay attention to tooth decay, the residual roots and crowns are relatively sharp, and their tongues are constantly rubbed when they speak or chew food, which causes serious diseases in the long run. Especially for those who live in remote areas with limited economic conditions, the condition exists repeatedly in the mouth, but they have not been to the hospital for consultation and treatment, and as a result, they miss the best time for treatment. When they really go to the hospital for treatment, the condition has changed from mild to severe, and the treatment cost also brings a heavy financial burden to the patients. Quit bad habits and pay attention to oral and dental disease is the fundamental way of prevention Many bad habits in life can effectively reduce the occurrence of oral diseases if they are changed, the disease occurs less, the possibility of deterioration is naturally less. The following points must be done seriously. First of all, pay attention to oral hygiene is the most fundamental way Brush your teeth every morning and evening, and rinse your mouth after meals. Those who have a lot of tartar need to clean it in time. If the hygiene is really good, tartar will not be there. Gum periodontal and dental and mucosal diseases can then be effectively prevented. Secondly, for the dentition or periodontal disease that already exists, it is necessary to go to the regular hospital for timely treatment If there is a cavity, it should be filled and repaired at an early stage, and the residual roots and crowns that can be repaired and utilized should be treated and repaired in a timely manner. Third, once found benign lesions or pre-cancerous lesions, should be timely consultation The need for surgery should also cooperate with the doctor, and later attention to regular observation. Do not believe in the “charlatan” so-called cure-all or ancestral secret recipe and other frivolous medical advertisements, in order to prevent the irregular diagnosis and treatment caused by a small disease into a big disease, and in serious cases, it may lead to a tragedy of “people and money”. Fourthly, quit smoking, alcoholism and other bad habits Strengthen physical exercise, improve nutrition, change bad habits such as work and rest, and eat more fresh fruits rich in vitamins and with anti-cancer and anti-cancer effects, which are also very important for the prevention of tongue cancer. Finally, middle-aged and elderly people can not be sick without medical treatment, young people should also be more care for elderly parents, warm and joyful care more, energy can be normally distributed, then including the other extreme: no disease hypochondriacs, can also be greatly reduced.
