Patient: A lump was found in the middle of the sublingual area and was diagnosed as highly differentiated squamous cell carcinoma, with signs of loose bleeding from 2 surrounding teeth. A small foreign body was found under the tongue around October, but I did not care about it at that time, and on January 23, 2009, I underwent partial excision of the sublingual and mandibular parts and removal of the mandibular lymph, and took pathology from 10 points around the lesion, and no cancer cells were found. What is the best treatment plan to prevent recurrence after surgery for this condition? How long after discharge from the hospital should I receive radiotherapy or chemotherapy? Highly differentiated squamous cell carcinoma has now been discharged from the hospital after surgery. Doctor: Hello! Your tumor stage T2N0M0 is relatively early, pathology is highly differentiated, malignant degree is low, and there is no lymphatic metastasis. Regular review is enough and radiotherapy is not needed. Usually, we should pay attention to avoid spicy and hot stimulating food, quit smoking and alcohol (you can drink a small amount of red wine), and treat bad teeth in time. Any lumps in the oral cavity and contralateral neck should be reviewed in time. The success rate of early tongue cancer cure is over 80%. It is recommended to see a regular Chinese medicine practitioner for treatment.
