What is a Thyroid Biopsy?
A thyroid biopsy is a medical procedure in which a small section of tissue from the thyroid is removed for examination. Biopsies are commonly ordered to determine the cause of a thyroid nodule, or to research a patient’s goiter. Having a request for a thyroid biopsy is not a cause for panic; an estimated 95% of thyroid nodules are benign, so the biopsy is being used primarily for patient safety, to confirm that there is not a cause for concern. If there is a cause for concern, having a biopsy early will increase the probability of a good prognosis.
