[|Human|] I have a small lump between the base and middle of my neck on the left side. ENT said no need for biopsy and watch to make sure it doesnt change size. Is that okay? It moves around and doesnt hurt when you touch it but sometimes has pain around it. Just want to be assured, not in denial.
[|AI|]  Welcome to Chat Doctor .1. Most possible cause is lipomatous lesion (fat containing) according to your description.2. But second possible cause will be infective etiology - thinking in terms of pain.3. In this case I would have done in this way - examine first, then ask for an ultrasound neck which will help me to know the nature of the lesion, its source and extensions.4. As it can be from thyroid, vascular and so on.5. Yes biopsy not needed but get the ultrasound done and depending on the nature of the lesion / lump keep followup. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
