Thyroid cysts usually do not affect the natural survival of patients. Smaller cysts usually do not require special treatment, while larger cysts with symptoms of pressure can be treated surgically with less postoperative effects and regular review of thyroid function. Most of the thyroid cysts are benign. If the cysts are small, less than 3 cm in diameter, and there are no uncomfortable symptoms, no special treatment is needed, and close observation and follow-up are sufficient. If the cyst is large and presses on the trachea causing dyspnea or is accompanied by other uncomfortable symptoms, surgical intervention is required. If the cystic mass is cystic solid, attention needs to be paid to observe the size and shape of the cystic solid mass, there is a certain risk of malignancy at this time. If the solid component is large, greater than 1.5cm or more, and the thyroid ultrasound cannot identify benign or malignant, ultrasound guided fine needle aspiration can be performed to further clarify the benign or malignant nature, and surgical intervention is needed if necessary. Therefore, if you have a thyroid cyst, there is no need to worry blindly. You should go to the endocrinology department of a regular hospital as soon as possible and undergo relevant examination and treatment with the help of a physician, which usually has no effect on your life expectancy.
