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. 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. According to the degree of pathological differentiation, squamous cell carcinoma can generally be divided into grade III: grade I is highly differentiated and has a low degree of malignancy; grade III is poorly differentiated and has a high degree of malignancy; undifferentiated cancer has the highest degree of malignancy. The incidence of gingival cancer in my country is relatively high. According to statistics from Shanghai Second Medical University, it ranks first in the composition ratio of malignant tumors, and most of them are highly differentiated squamous cell carcinomas.
