Thyroid Nodules
You are more likely to develop a thyroid nodule if:
- You are older. Thyroid nodules are more common in older people.
- You are female. Women are more likely than men to develop thyroid nodules.
- You have been exposed to radiation. Exposure to environmental radiation or past radiation treatment to your head, neck, and chest (especially during childhood) increases your risk for thyroid nodules.
- You do not get enough iodine. Iodine deficiency is rare
in the United States but it is common in areas where iodine is not added to
salt, food, and water. An iodine deficiency may result in an enlarged thyroid
gland (goiter
), with or without nodules. - You have Hashimoto's thyroiditis. Hashimoto's thyroiditis can cause an underactive thyroid gland (hypothyroidism).
- One or both of your parents have had thyroid nodules.
