Thyroid Nodule


This is a growth of cells in your thyroid. The thyroid is a hormone-producing gland in your neck. It makes hormones that help control many activities in your body. A thyroid nodule can interfere with your thyroid's function.


We often don't know why thyroid nodules form. They happen in people who don't get enough iodine in their diet. But this is uncommon in the developed world. Nodules can result from Hashimoto's disease, a thyroid disorder that causes inflammation of the thyroid. And, a nodule can result from a cyst in thyroid tissue. Sometimes, but not often, a thyroid nodule is cancerous.


Most thyroid nodules don't cause any symptoms, but some do. A large nodule can get so big that you can see it or feel it. It can cause changes in your voice. It may be painful. It may interfere with breathing or swallowing. And, nodules that interfere with the thyroid's hormone production can cause a wide range of symptoms throughout the body. Ask your doctor for a full list of symptoms.


Treatment is based on the type of nodule. Some can be treated with radioactive iodine and anti-thyroid medications. Cancerous thyroid nodules may be treated with alcohol injections. You may need surgery to remove some or all of your thyroid. Your healthcare provider will create a care plan that's right for you.
