Cancer is the most common malignant tumor in the oral and maxillofacial region, and squamous cell carcinoma is the most common cancer. In my country, oral and maxillofacial squamous cell carcinoma mostly occurs between the ages of 40 and 60, and is more common in men than in women. Gingival cancer, tongue cancer, cheek cancer, palate cancer and maxillary sinus cancer are common, while jaw cancer is relatively rare. Oral cancer accounts for 1.45-5.6% of all malignant tumors in the north of the Yangtze River in my country, and 1.75-5.18% in the south of the Yangtze River. In India, it accounts for more than 40% of all malignant tumors in the body. Jaw cancer mainly occurs in the remaining cells of the enamel epithelium of the tooth germ. These epithelial cells can remain in the periodontal ligament, cyst lining, and from the malignant transformation of ameloblastoma. In terms of histological type, it can be either squamous cell carcinoma or glandular epithelial carcinoma.
