Firstly, we recommend that patients with thyroid cysts should consult the endocrinology department first to assess thyroid function, to determine if there is hypothyroidism, hyperthyroidism, or normal thyroid function. Then, perform a thyroid ultrasound to evaluate the size of the cyst and its relationship with surrounding tissues, etc. Therefore, patients with thyroid cysts should first visit the endocrinology department. If surgical intervention or other further treatments are necessary, then a visit to the breast and thyroid department is needed. However, it is first essential to assess the function and local conditions of the cyst in the endocrinology department before deciding on the next step of treatment.
