I noticed a small painless lump under my jaw about a year ago and consulted a GP, who then refered me to a specialist. FNAC was done, and the report read:"Examination revealed a firm, circumscribed, mobile, non-indurated mass measuring 1.5x1.5 cm at the left submandibular region. Smears show scanty material composed of a mixed population of lymphoid cells. No malignant cells detected. Cytological feature are consistent with reactive hyperplasia". Nothing was done as I was told that it was not cancerous. The lump remained but sometimes subsided and never painful at all.

However, couple pof months ago the swelling suddenly became bigger and very painful. After checked-in into hospital, CT scan of the neck was done that according to the report suggested lymphadenitis with abscess formation. Surgery was performed under ga. incision and drainage did not reveal much pus, a whole lymph node was removed for histopatology examination. The diagnosis was necrotising lymphadenitis. Rebiopsy was suggested if new nodes appear.

I'd like to know if this is cancerous or will it lead to cancer of the lymph nodes. I would very much appreciated your advice. Thank you.
