[|Human|] Good evening! I have a hard growth at the left base of my neck (the back). It doesnt hurt at all, but it bothers me everytime I see it. I did some work with a cargo company for four years at JFK Airport where I have handled radioactive materials and other infectious stuff. There was even a white powder spill (hazmat) in our warehouse once around 2003, and I know that I have breathed that stuff for a good while before we became aware of its presence on the floor of our location. Could this be a benign tumor or a cancer in the making? Whats worse, I dont have insurance now.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have enlarged lymph node.  It can be due to reactive hyperplasia, tuberculosis or lymphoma.  Or you may have some soft tissue tumor like lipoma or neurofibroma or other mass.  You should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. 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.
