The cure rate of cancer varies in different countries, different ethnic groups and even different regions. According to authoritative statistics, most of the reported cancer cure rates in China are centered between 50% and 60%, which is in the middle or upper level of cancer treatment. Cancer cure rate is related to many factors. For example, oral cavity squamous carcinoma, the degree of malignancy is also known as biological characteristics, and its cure rate is related to the degree of malignancy and the early or late diagnosis and treatment, i.e., it is related to the early or late clinical staging. Clinically, oral cavity squamous carcinoma is divided into four stages, which are clinical stage I, II, III and IV. In clinical stage I and II, i.e. early stage, the cure rate is relatively high; in clinical stage III and IV, i.e. middle and late stage, the treatment effect is poor and the cure rate is lower than 50%-60%. In addition, it is also related to the medical level, whether the professional oncology treatment plan or measures are properly implemented, and whether the treatment level is high or low is also directly related to the cure rate. Therefore, for the treatment of oral cancer patients, early detection and early treatment are advocated in order to get better therapeutic effect. Therefore, attention should be paid to it.
