If part or all of your thyroid gland needs to be surgically removed because of cancer, radioactive iodine may be used to destroy any thyroid tissue or cancer cells that remain after surgery.
If you have a thyroid nodule:
Take any thyroid hormone medicine your doctor prescribes at the same time each day and do not miss a dose.
Follow your doctor's advice for getting your blood checked for thyroid hormone levels.
Call your doctor if you have symptoms of hyperthyroidism, such as feeling nervous, having a fast heartbeat, sweating more than usual, and losing weight. Sometimes, hyperthyroidism develops from taking thyroid hormone medicine or when a noncancerous nodule starts making too much thyroid hormone.
Call your doctor if you have symptoms of hypothyroidism, such as feeling tired, feeling cold when others do not, and gaining weight. Hypothyroidism can develop after you are treated with radioactive iodine or you have surgery.
Schedule regular checkups with your doctor. Even noncancerous nodules need to be looked at by your doctor on a regular basis.
Treatment if the condition gets worse
If your thyroid nodule gets bigger, your doctor may recommend another fine-needle aspiration to see whether the nodule has become cancerous. If your nodule has become cancerous or appears to be cancerous, your doctor will probably recommend surgery (thyroidectomy) to remove some or all of your thyroid gland. You may also need radioactive iodine.
