(Thyroid Nodule)

What Are Thyroid Nodules?

  • The main function of the thyroid gland in the neck is to make thyroid hormone, which is essential for normal growth and metabolism.
  • Nodules are simply lumps which are either solid or fluid-filled. Goiter is simply a term for an enlarged thyroid gland. Autopsy studies have revealed that up to 50% of all adults die carrying at least one thyroid nodule. These people may or may not have been aware of the presence of their thyroid nodules.
  • Thyroid nodules are found more commonly as people age.
  • Most thyroid nodules are benign and not cancerous.
  • Only 5% of all thyroid nodules will be discovered to be thyroid cancer.
    • Finding cancer in a thyroid nodule is more likely in a person younger than age 30 or older than age 60 years.
    • However, it is important to remember that only a small percentage of people with thyroid cancer die as a result of their thyroid cancer.
