The objective of this study was to summarize the evidence regarding the diagnostic accuracy of growth during follow-up of benign thyroid nodules for thyroid cancer. The body of evidence linking nodule growth with thyroid cancer during the follow-up of benign nodules warrants very low confidence.
In the era of high-value health care, the commonplace practice of following benign thyroid nodules with serial ultrasound assessment of growth to diagnose cancer can be questioned, calling for imminent evaluation.
