    Description

    A thyroid nodule is a lump in the thyroid gland. Most are benign (not cancerous). In this procedure, a thin wire is inserted into the nodule under local anaesthetic and guided into position using ultrasound. Microwaves from the wire heat the nodule to destroy it (ablation). The aim is to make the nodule smaller, relieve symptoms and improve appearance.
