I have a nodular colloid goitre. Fnac : the smear shows follicular epithlial cells singly and in small monolared groups, no malignancy, whts trtmnt.

No active treatment. Benign thyroid nodule. It needs periodic evaluation and follow up: biochemical : TSH and free t4, this gives functional status of thyroid gland. Thyroid ultrasound : any change in size and character of nodule. Fine needle aspration, if indicated. This can be done every 6 months/yearly.
Close observation. Need observation if needed repeat fna. See your doctor for follow up care.
