[|Human|] A year ago a friend was diagnosed with squamous cell carcinoma in her throat. She underwent 7 weeks of intense radiation & 2 chemo sessions. She has been slowly recovering only to discover a hard golf ball size lump just above her collarbone on the same side. Could her cancer be recurring?
[|AI|]  Hi, dear. I have gone through your question. I can understand your concern.  If your friend had squamous cell carcinoma then its definite chance of recurrence. His hard mass may be recurrent squamous cell carcinoma. You should go for biopsy of that lump.  If it is recurrent or metastatic disease then consult your oncologist and take treatment 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.
