<s>[INST] My husband was diagnosed with cancer in his tongue. We were told it is growing down into his tongue and he needs to have at least 1/3 of his tongue removed. What is the name for this cancer so I can learn more about it. We were told carcinoma but there must be more to it. Surgery scheduled for May 30th [/INST] Thanks for your question on Chat Doctor. The most common cancer of tongue is squamous cell carcinoma. Type of cancer is determined by biopsy and histopathological report. So in his histopathological report type of cancer must be mentioned. So check it for the type of cancer. Tongue cancer has excellent prognosis if early surgery is done. In the treatment unblock resection (resection of whole mass with clear margins with involved lymph nodes) is done. And post-operative chemotherapy and radiotherapy is needed to prevent distal as well as local recurrence. So surgery is must. </s>
