<s>[INST] Hello, my name is Shonda. I have a lump that seems to be growing rapidly. Its on my tonsil...I sceduled a tonsilectomy for April 19 but I m concerned the growth pace is making that unlikely. I m nervous... what is the percentage that this could be cancer? [/INST] Hi, dairy have gone through your question. I can understand your concern. You have lump on tonsil.  Your age, habits and many other factors are important to know the chance of cancer.  You should go for biopsy of that lump on tonsil.  It will give you exact diagnosis whether it is squamous cell carcinoma or something else.  Then you should 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. </s>
