Ablation refers to radiofrequency ablation, which can be performed for 3 categories of thyroid nodules. The advantages of radiofrequency ablation are that the procedure is short, less invasive, less scarring, and does not damage normal thyroid tissue. Radiofrequency ablation can also be performed at this time if the original procedure has been performed within the nodule and the nodule forms again. Thyroid nodules are categorized into benign nodules and malignant nodules. For benign nodules smaller than 3cm, radiofrequency ablation is more effective, less damaging to the body and faster recovery. However, for nodules larger than or equal to 3cm, the tumor is larger and can usually be seen or felt on the body surface, often requiring surgical resection to cure. Thyroid nodules 3 types of benign nodules are more suitable for ablation treatment, when there is a malignant nodule, it should be timely to the regular hospital surgical removal.
