Oral mucosal cancer is mainly squamous cell carcinoma, which is potentially curable. Generally, it can be cured in early stage, but the chance of cure in late stage is not great. 1. Early stage of oral mucosa cancer: Early stage of oral mucosa cancer is usually treated mainly by surgery and auxiliary treatments, such as local radiotherapy and biotherapy, etc. If there is no distant tumor metastasis, lymph node scavenging can be chosen. If there is no distant tumor metastasis, lymph node dissection can be chosen and local radiotherapy can be carried out according to pathological results. It is possible to achieve clinical cure by active treatment in this period. 2. Advanced stage of oral mucosa cancer: in advanced stage, the tumor often has distant metastasis or invades blood vessels, so surgery is ineffective and can only delay the survival time of patients and reduce their pain. Whether oral mucosal cancer can be cured or not needs to be combined with the patient’s condition, and after finding abnormalities, the patient should be treated under the guidance of regular doctors in time.
