[|Human|] I have a hard, painless, lump under my jaw (towards the back.) It has been there for about 3 months...What could it be? I have spoke with a dentist, who wasnt sure and referred me to an oral surgeon; however, it is taking a long time to get an appointment scheduled...
[|AI|]  Hi. Thanks for the query. A hard painless lump under the jaw can be due to a number of reasons like 1. If it is a painless and freely movable lump it can be due to lymph node swelling which is commonly seen in case of near of distant infection in the body.2. If it is a diffused swelling which increase during eating it can be due to blocked duct of submandibular salivary gland.3. A swollen lymph node can be due to Malignant changes in lymph nodes leading to formation of a LYMPHOMA. I would suggest you to consult an Oral Pathologist if surgeon is not available and get evaluated. In case if it is due to blocked salivary duct removal of obstruction can help... In case it is a lymph node, and you do not have any ongoing or recent history of infection then a Biopsy of the lymph node has to be done to confirm the diagnosis. Hope this helps. Regards.
