[|Human|] I have some questions about cancer..my brother was just diagnosed with squamous cell cancer of the tonsil and at least one lymph node that they can see from the ct scan. they say that is 90% curable. I was just reading on here some info. about it.. what do you say?
[|AI|]  Hello;Squamous cell carcinoma of tonsil is staged according to size of lesion in tonsil and number and size of lymph nodes. Stage can be from 1 to 4. Since you said he has lymph node, he has at least stage 3 cancer. Regarding treatment, the best treatment modality for your brother is concurrent radio-chemotherapy in which radiation is given to tonsil and neck node along with chemotherapy. Radiation is usually administered 5 days a week for around seven weeks. Results are pretty good for this treatment however cure rates depend on exact stage of disease and response of disease to treatment.
