What are they?
Thyroid nodules are solid or fluid-filled growths within the thyroid gland, which is a gland located low and in the center of the neck. Most nodules are benign (non-cancerous), but should be appropriately evaluated with imaging and, sometimes, a minimally-invasive biopsy.
How are they treated?
Very small nodules and ones that are benign on biopsy can be followed with imaging to ensure there is no change over time. Sometimes, a biopsy shows results that are unclear. Depending on various factors, the biopsy can be repeated. However, there is sometimes a need to remove a portion of the thyroid gland to make a final diagnosis.
