[|Human|] I do not know whether or not to be concerned about a lump in my neck.  It has been there for several years now.  However, lately I have begun to experience some other disturbing symptoms.  I would like to know if the lump is a lymph node or my thyroid. 55-year-old female, 190 lbs. BMI 29, otherwise healthy as an ox.
[|AI|]  Welcome to Chat Doctor .1. In this case first I would examine you, and locate the lesion.2. After that I would perform an ultrasound scan - cheap / non-invasive / no radiation.3. It will help to find out weather it's from your thyroid / lymph node / brachial cleft cyst / lymphocyte.4. Ultrasons will also help to evaluate weather It's operable or not - involvement of the neck vessels.5. So you better take an appointment with your doctor and accelerate the process.6. Hope it helps you. Anything to ask ? Do not hesitate. Thank you.
