I had a fine needle aspiration of a lump near my left parotid. It's a painless lump, but is not going away. It took 3 weeks to get the results back and then I got a call from the ent consultant to say it's a benign lump, however I have had a patient summary from my doctor's and in there it has said that "FNA- yielded slightly mucoid material, concerning mucoepidermoid carcinoma. No immediate complication" my understanding of the term mucoepidermoid carcinoma is that it's cancerous? However the consultant didn't mention this and said they wouldn't look to operate on it unless it grew bigger or became inflamed/infected. I'm a bit worried now as to what is correct or not and what to do. The lump is still there and has been for about 3 months now.
