The Value of Fine-Needle Aspiration Biopsy in Subcentimeter Thyroid Nodules

Abstract

The incidence of cancer in thyroid nodules < 1 cm does not appear to be lower than in larger nodules and may even be higher. Physicians should consider obtaining biopsy samples from subcentimeter hypoechoic nodules that contain microcalcification and have a relatively round shape (LA/SA < 1.5).
