[|Human|] I have these two swollen round bits under my jaw on each side, and I feel this dull pressure that is hard to describe. It feels like something is caught in my throat and at the same time its just a little achy. I can talk fine and I have no issue swallowing. Im worried this might be due to my smoking? How can I tell if its cancer?
[|AI|]  Hi and welcome to Chat Doctor. Only biopsy can show for sure what it is, but usually this is just a swollen lymph node due to respiratory infection. But if there is redness around it, or it is fixed to background or growing fast then you should visit specialist. If this is soft and movable then it can be lymph node or lipoma. To be sure you can do ultrasounds with needle biopsy and see exact case. Wish you good health.
