[|Human|] My brother has been diagnosed with cancer.  There is a lymph node in his neck that has tested positive for cancer.  However, his doctor believes the originating site may be in his tonsils.  He is scheduled to have his tonsils removed immediately, then undergo chemo and radiation, then removal of the lymph node.  What does this all mean?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern.  He has tonsil cancer with lymph node metastasis.  He should go for tonsillectomy followed by chemotherapy and radiotherapy according to need.  It depends on stage and type of cancer. But surgery is the first step.  Consult your doctor and plan accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
