Larger thyroid adenomas or those with hyperthyroidism usually require surgical resection, and oral medication is ineffective and usually does not reduce the size of the adenomas, while smaller adenomas do not need to be treated. Thyroid adenomas are mostly benign, if the size is small and the thyroid function is normal, they can be observed and followed up without treatment. However, some thyroid adenomas are large or have an autonomic secretory function that can lead to hyperthyroidism and need to be surgically removed. This kind of adenoma causes hyperthyroidism, taking anti-thyroid medication is generally not effective. There is also a part of thyroid adenomas that may become cancerous and should be decided by a professional doctor according to the condition to decide whether or not to treat it surgically. Generally speaking, there are few recurrences after surgical resection, and those that recur can be treated with surgery again. Thyroid adenomas are not effective with oral medications and usually do not shrink, so patients are advised to seek medical attention promptly.
