The thyroid gland is located in the middle of the lower neck, below the larynx, and wraps around the front half of the trachea. You cannot always feel a normal thyroid gland.
Thyroid nodules are solid or fluid-filled lumps that form within the thyroid. Most thyroid nodules are not noticed until your doctor discovers it during a routine medical exam. However, some thyroid nodules may become large enough to be visible or make it difficult to breathe or swallow.
Most thyroid nodules are not serious and do not cause symptoms. Although only a few nodules are cancerous, ask your doctor to evaluate any unusual swelling in your neck.
Treatment options depend on the type of thyroid nodule you have.
