<s>[INST] help! my daughters family doctor sent us to a surgeon to have a lump looked at between her neck and collar bone within 30seconds he says its a mass of tissue either being a salivary gland that is not suppose to be there or cartilage that has formed.....im worried and was expecting an x ray or something now they want to do surgery....possible to be determined this easy/fast??? [/INST] Hi, dairy have gone through your question. I can understand your concern. Your mass may be due to enlarged lymph node or salivary gland or some other cause.  Most easy and fast way is FNAC.  You should go for fine needle aspiration cytology study of that mass.  It will give you exact diagnosis regarding cause.  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>
