Task: Answer Verification
Input (English): Question: Is diagnostic lobectomy routinely required to exclude malignancy in thyroid nodules greater than four centimetres?
Answer: Many patients with large thyroid nodules undergo thyroidectomy for symptom relief alone, regardless of their FNAC results. In such patients where other clinical indicators for thyroidectomy are not present, a benign FNAC result can reassure both patient and surgeon that mandatory surgical excision is not needed to exclude malignancy.
Output (English): no
