Thyroid cancer radiofrequency ablation surgery has the possibility of recurrence. Radiofrequency ablation surgery for thyroid cancer is to ablate and excise the lesion area through radiofrequency instruments, and there is a certain chance of recurrence after the surgery, which needs to be determined according to the type and stage of the tumor. If the tumor is of low malignancy, most of the patients can be cured by removing the cancer cells through surgery, and the recurrence rate in the later stage is relatively low; however, if the tumor is of high malignancy, recurrence is easy to occur after the surgery, and it is necessary to do a good job in regular checkups, radiotherapy, chemotherapy, etc. In addition, the stage will also affect the recurrence rate. In addition, the staging will also affect the recurrence rate, the earlier the radiofrequency ablation surgery, the higher the cure rate and the lower the recurrence rate. It is recommended that patients strictly follow the doctor’s instructions for regular checkups, maintain good dietary habits, and strictly follow the doctor’s instructions for medication in order to obtain a better prognosis.
