Hello. Thanks for posting your query. Well, without a clinical evaluation it would be difficult to determine the cause of the lump. Possibilities that may need to be considered include enlarge lymph nodes, lipomas, cysts, growths from underlying connective tissue etc. Swollen lymph glands are the most common cause of lumps on the neck. These glands enlarge in response to infections, both bacterial and viral. They also can enlarge as the result of a malignancy or autoimmune conditions, like lupus or rheumatoid arthritis. I would suggest getting this evaluated by doctor for an accurate diagnosis and appropriate management. You may get the FNAC (fine needle aspiration cytology) of lump done under his/her guidance. Wishing you good health.... Regards Dr Saurabh gupta.
