Hi, thanks for writing to HCM. Well, If I were your treating Doctor for this case of a neck lump on the thyroid area, I would come up with three possibilities, these include: 1. a colloid cyst of the thyroid! however, sometimes these cysts might contain cancerous cells also! 2. The second possibility is of benign and simple inflammatory conditions like lipoma or neurofibroma or a reactive enlarged lymph node; there is nothing to worry about these! Sometimes a lymph node might suggest cancer in the larynx/throat... 3. The last possibility is of sebaceous cyst or some other cysts like infected branchial cyst or lymphatic cysts! Nothing to worry about these also! Therefore, the treatment only depends upon the diagnosis! I suggest you to go for an FNAC /biopsy and ultrasound of the lump for confirmation and to relieve your concerns! Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
