Accuracy of FNA



Is a fine needle aspiration (FNA) sufficient to diagnose thyroid cancer or do should I have a biopsy of the nodule?


Kolin Hoff, MD, Endocrinologist at Penn Medicine responds,

In most cases FNA can diagnose malignancy or at least a suspicious nodule. In some cases only surgery can definitively diagnose a cancer. A biopsy that is read benign is correct about 97% of the time but may vary by institution.
