Repeat biopsy in patients with slow-growing thyroid nodules

Leonard Wartofsky

Should a fine-needle aspiration biopsy (FNAB) be repeated in a patient with a slow-growing thyroid nodule that was benign on a previous FNAB and shows no new risk features on ultrasonography?

Leonard Wartofsky, MD: With such a nodule, one would not be forced to repeat the biopsy based on professional guidelines. But I think most clinicians would opt to repeat it at least one time, and then, if again negative and not growing, simply follow the patient thereafter long-term.

Technically speaking, with a negative ultrasound, negative needle aspiration cytology, and no significant change in growth, one need not be worried about such a nodule.
