A thyroid nodule is a lump in the thyroid gland that moves up and down with the thyroid gland with swallowing movements. If a thyroid nodule does not require surgery, it can be followed up regularly in the relevant department to observe changes in the thyroid nodule and changes in thyroid function. For thyroid nodules that require surgery, you can visit the general surgery department and under the guidance of a surgeon, take the appropriate surgical treatment. There are a variety of thyroid disorders that can manifest clinically as nodules, such as inflammatory thyroid conditions, autoimmune and neoplastic conditions. Thyroid nodules are a common condition, especially in middle-aged women. They can be classified as benign or malignant, with benign nodules accounting for the majority and malignant nodules for less than 5%. The nodules are classified into “hot nodules” and “cold nodules” according to their ability to take up radionuclides. “Hot nodules are functionally autonomous thyroid nodules and are almost always benign. “Cold nodules, on the other hand, have the potential to be cancerous, but multiple cold nodules are mostly benign adenomas or nodules, and if there is bleeding or cystic changes in the nodule, it may also appear as a cold nodule. If you have a thyroid nodule, it is recommended that you go to a regular hospital to receive treatment, so that you do not miss the best time to treat it, so as not to delay your condition. You should make reasonable arrangements for your life and work, and eat less food with high iodine content.
