Thyroid tumors are benign thyroid tumors that can be cured. Thyroid adenoma is a lump in the neck that moves up and down with swallowing activity. It is usually tough to touch and does not cause any pain, so it is easy to be ignored and does not show any signs in the early stage. Thyroid tumors may also increase rapidly in size within a short period of time, usually due to bleeding within the adenoma, which may affect the patient’s breathing and even cause hoarseness and difficulty in swallowing, etc. In this case, timely surgery is required. Thyroid tumors have a certain rate of malignancy, with a chance of malignancy of more than 30%, and surgery is usually recommended for thyroid tumors over 3cm.
