Some people do not even know they have thyroid nodules as they may not cause any symptoms. However, if left untreated, large nodules can cause complications and interfere with thyroid hormone production.

What Causes Thyroid Nodules?

The exact cause of thyroid nodules is not always known, however a few potential causes include:

  • Iodine deficiency
  • Autoimmune diseases
  • Thyroid nodules can be due to cysts, benign tumors, and tumors that are cancerous
  • Hashimoto’s disease
  • Exposure to radiation such as radiation therapy
  • Genetic inherited conditions
  • Infections of the thyroid such as tuberculosis
