Thyroid nodules are categorized into benign and malignant nodules. Most benign nodules are asymptomatic, while larger nodules may present with compression symptoms such as difficulty in swallowing and breathing. Thyroid nodules that are small in size and benign usually do not show obvious symptoms. If the thyroid nodule grows faster and the nodule is too large and compresses the surrounding tissues, such as nerves, esophagus, trachea, etc., symptoms such as hoarseness, dysphagia, dyspnea, and so on, will occur. Thyroid nodules may also have symptoms related to distant metastasis if they become malignant. Patients should go to the hospital in time when the above symptoms occur.
