[|Human|] For almost 7 years, I have had a bump on the right side of my neck that is probably a lymph node.  It almost never changes, and even gets bigger when I am sick and smaller again when the infections resolve.  Is this something I should worry about?  A new doctor I have never seen before basically seemed worried about it and sent me for a CT which I am waiting still to schedule.
[|AI|]  Welcome to Chat Doctor .1. Lymph nodal enlargement is seen in case of any infection / inflammation, any benign and malignancy causes.2. As you giving history of enlargement after any infection - so its of infective etiology (most possible cause).3. The doctor might be suspecting / want to rule out malignancy.4. A contrast enhanced computer tomography will help in identifying the mass lesions / malignancies.5. An FNAC - fine needle aspiration cytology might be needed for further evaluation. Good luck. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
