Abstract
The 2015 guidelines from the American Thyroid Association for adults with thyroid nodules and differentiated thyroid may be particularly important in minimising potential harm from overdiagnosis and overtreatment of thyroid tumours by providing more restrictive indications for biopsy of thyroid nodules, by considering active surveillance programs, as an alternative to surgery, for papillary microcarcinomas, and by recommending more conservative surgical approaches and a more judicious use of radioiodine.
