Small cystic solid thyroid nodules may have no obvious symptoms, but if they are large enough to compress other organs and tissues, symptoms such as difficulty breathing and hoarseness may occur. Cystic solid thyroid nodules are small and benign, and usually do not cause significant symptoms. If the growth rate of cystic solid thyroid nodules is fast and the size of the nodule is too large and compresses the surrounding tissues, such as the trachea and esophagus, symptoms such as hoarseness, swallowing disorders, and difficulty in breathing may occur. Cystic solid thyroid nodules may also have symptoms related to distant metastasis if they become malignant. It is recommended that patients with cystic solid thyroid nodules be treated under the guidance of a doctor.
