Thyroid Surgery

Thyroid Nodules

  • What are thyroid nodules?
    A thyroid nodule is an abnormal growth of thyroid cells within the thyroid gland. Most of the time the cause is unknown.
  • How common are thyroid nodules?
    Thyroid nodules are very common in the general population. 50-70% of adults have thyroid nodules and the incidence increases with age. Most thyroid nodules do not produce any symptoms and go undetected.

  • If I have a nodule, do I have to be concerned about cancer?
    The majority (90-95%) of thyroid nodules are benign – meaning they do not contain any cancer cells.

  • How can my nodules(s) be evaluated?
    The best test for evaluating the thyroid is a dedicated thyroid and neck ultrasound by an experienced radiologist, endocrine surgeon, and/or endocrinologist. Many times a fine needle aspiration biopsy of the nodule will be performed for further evaluation.

  • Do all thyroid nodules need to be surgically removed?
    No. There are two main reasons why your endocrinologist or surgeon will recommend surgery for thyroid nodules.
    • Concern for cancer or an “indeterminate” biopsy (see Thyroid cancer section)
    • You are experiencing obstructive symptoms from a very large nodule(s) such as trouble breathing when you lie flat or trouble swallowing solid foods.

  • Is there another treatment besides surgery for thyroid nodules?
    No. Studies have shown that medication does not shrink thyroid nodules.
