Thyroid cysts usually do not heal on their own. Thyroid cysts are cystic masses in the thyroid gland that contain liquid or semi-solid material. Some patients may have no obvious symptoms, while larger thyroid cysts that cause compression symptoms may have symptoms such as difficulty swallowing, hoarseness, and may be accompanied by symptoms of swelling in the neck. Thyroid cysts usually do not heal on their own. Small and asymptomatic cysts can be examined regularly, while larger cysts can be treated with ultrasound-guided aspiration, and surgical resection is recommended if the swelling increases rapidly or is suspected to have a tendency to malignant changes. Patients diagnosed with thyroid cysts should actively cooperate with doctors for treatment, which can help improve the prognosis.
