Discharge Instructions for Fine-Needle Thyroid Biopsy
You had a procedure called fine-needle thyroid biopsy. This biopsy was done to assess a nodule or cyst in your thyroid gland or enlargement of the thyroid. During the biopsy, a very thin needle is inserted through the skin into the gland. The needle is used to remove a small amount of tissue from the gland. (This may be done more than one time to be sure to get cells from all parts of the nodule.) Or the needle is used to drain fluid from a cyst. The tissue or fluid is then studied in a lab.
