Oral cancer patients often worry whether the tumor will recur after surgical treatment and how they should deal with it after recurrence. Oral cancer is a malignant tumor, but because it is easy to be detected and patients seek medical treatment in time after detection, most patients have a chance of surgical treatment. At present, it is considered that oral cancer can be cured if there is no recurrence within 5 years after surgery, and the 5-year survival rate of oral cancer can reach more than 60%, so patients should go to regular hospitals in time after discovering abnormalities in the oral cavity. Patients who have undergone surgical treatment should pay great attention to the time of each review and postoperative self-screening. One or two years after the surgical treatment is the high incidence of recurrence and metastasis, especially 3 or 4 months after the surgery is more concentrated recurrence, such as timely detection may still have the opportunity to receive surgery again to cure. Generally speaking, the postoperative period should be reviewed once a month in the first year and once every 2 months in the second year. Patients should also pay attention to the situation in the oral cavity and bilateral neck (i.e., neck), and can do their own neck search with the doctor’s guidance. If they find any unexplained lumps appearing in the neck, develop headache symptoms or find any oral abnormalities, they should be reviewed immediately. The review time is usually arranged according to the condition and the opinion of the attending physician, and should be done on time. Some patients need to be reviewed for a longer period of time, or even regularly throughout their life. Only in this way can the doctor keep track of the patient’s condition, detect abnormalities and deal with them in a timely manner. Many patients are not able to do the above more frequent follow-ups due to geographical factors, and some patients also give feedback to their doctors on their lesions by letters and the Internet, but due to the lack of professional knowledge, the information provided by patients is not accurate, so it is still recommended that patients, if they suspect signs of recurrence, should go to a specialist in a timely manner, and patients from overseas can also first go to the local hospital for preliminary examination and decide the next step according to the examination, which not only ensures your health but also saves the time of patients and doctors.
