Tumors on the Tip of the Tongue: Cancers that Grow in the Mouth Talking about oral cancer may be unfamiliar. But when it comes to Sigmund Freud, the famous psychologist, probably no one knows about it. Unfortunately, this great man suffered from oral cancer in his later years and spent the rest of his life with a very poor quality of life. The Current Status of Oral Cancer Oral cancer refers to malignant tumors that occur in the soft and hard tissues of the oral and maxillofacial region. According to the clinical classification recommended by the International Union Against Cancer (UICC), most of the head and neck cancers are located in the oral and maxillofacial region According to the literature, the estimated standardized incidence rate of oral and pharyngeal malignant tumors in China is 8.7/100,000 (male) and 6.0/100,000 (female). According to the tumor registry in Shanghai, the prevalence of oral and maxillofacial carcinomas ranged from 2.5 to 3.4 per 100,000 (females) and 3.2 to 3.6 per 100,000 (males). In the composition ratio, oral and maxillofacial tumors were 8.2% of systemic tumors. Oral and maxillofacial malignant tumors mostly occur in males, and the male-to-female ratio in domestic statistics is 2:1. However, in recent years, the incidence of oral cancer in females has a tendency to increase significantly. However, in recent years, the incidence of oral cancer has increased significantly in females. Oral cancer is common in China with buccal cancer, tongue cancer, gingival cancer, palate cancer, maxillary sinus cancer, etc. Lip cancer, especially facial skin cancer, is relatively rare. However, similar to the West, the incidence sites in China have also changed. in the 60s, the order of the primary sites of oral cancer was as follows: gingival cancer, tongue cancer, buccal mucous membrane cancer, etc., but since the 80s, tongue cancer has jumped to the first place, and gingival cancer has retreated to the third place. Moreover, there is a trend of increase in the number of tongue cancer cases among females and patients under 40 years old. Another obvious change is that the cases of malignant lymphoma of oral and maxillofacial region have increased significantly, and unlike western countries, there are significantly more non-Hodgkin’s lymphoma than Hodgkin’s lymphoma in China. Overall, the survival rate of oral cancer in China should be among the top in the world. The recently reported 5-year survival rate of oral cavity squamous carcinoma is around 65%, and the addition of traditional Chinese medicine after surgery can increase the 3-year survival rate to 74.5%; the 10-year and 1555-year survival rates of salivary adenocarcinoma are 63.3% and 59.1%. Prevention of Oral Cancer 1. Avoid unnecessary prolonged exposure to light to prevent lip cancer. 2. 2. Avoid smoking and drinking. 3. Patients wearing dentures: if you find any pain or inflammation in the tissues under dentures, you should consult doctor in time. Strive for early detection, early diagnosis and early treatment of cancer and insist on regular examination. 4. Balanced diet, coarse and fine combinations, reasonable nutrition: don’t drink or eat too hot water and food to avoid stimulating oral tissues. 5. Extract the residual roots and crowns of teeth (teeth that cannot be repaired): wear good dentures that do not irritate the tissues. 6. Develop good oral hygiene habits: brush your teeth frequently. Pay attention to the balance of nutrition, timely treatment of residual roots and crowns, and removal of undesirable stimuli. Self-examination of oral cancer Improve one’s ability to recognize precancerous lesions: achieve early detection, early diagnosis, timely treatment and prevention of cancerous lesions. Through self-examination, those who find the following abnormalities should seek medical treatment immediately. Unexplained numbness and pain in the mouth, jaw, pharynx and neck.
