The size of thyroid nodule is 18mm x 13mm, and whether it is serious or not should be judged in conjunction with the nature of the lesion and clinical symptoms. Corresponding thyroid nodules shown to be benign through puncture biopsy are not particularly serious conditions, and generally do not require special treatment if there are no obvious symptoms. For benign thyroid nodules accompanied by compression symptoms, radical resection can be done through surgery, which can reduce the pressure on the surrounding tissues and hormone levels, and most of them can be clinically cured. Malignant lesions, which are relatively serious, should be staged and treated under the guidance of clinicians to prevent obvious peripheral invasion and distant metastasis. Thyroid nodules are accompanied by obvious endocrine abnormalities and peripheral compression symptoms, which require timely medical attention and standardized treatment under the guidance of clinicians to prevent delays in the condition.
