Thyroid cysts refer to thyroid nodules containing fluid and the vast majority are benign. Current treatments include sclerotherapy, surgical removal and chemical or physical ablation, etc. Consultation with a doctor is recommended. The treatment of thyroid cysts and the method of treatment depend on the nature and size of the cyst. For benign thyroid cysts, treatment is basically required only when localized pressure symptoms and cosmetic effects are present. Surgical excision is appropriate for significantly enlarged complex or recurrent cysts; chemical ablation and pharmacologic sclerotherapy are simple and easy to perform. For malignant thyroid cysts, surgical removal and regular follow-up are recommended. When a thyroid cyst is diagnosed, it is recommended to consult a doctor for targeted treatment and choose an appropriate treatment plan under the doctor’s guidance.
