Thanks for your question on Chat Doctor. Treatment of any cancer depend on its staging. And for staging we need to know exact size of the lesion, lymph nodes involved or not and Metastases to distal organs present or not. So in your friends' case we need to get done CT neck and PET scan to know the exacts tagging. And usually chemotherapy and radiotherapy is needed to prevent local recurrence and distal metastases.  So better to consult oncologist and start treatment.
