Thyroid Cancer Overview
The thyroid gland is located low in the front of the neck, below the Adam's apple. The gland is shaped like a butterfly and wraps around the windpipe or trachea. The two wings or lobes on either side of the windpipe are joined together by a bridge, called the isthmus, which crosses over the front of the windpipe.
Thyroid cancer occurs in all age groups, although its incidence increases with age, especially after 30 years of age. The more aggressive forms of thyroid cancer are more commonly found in older patients. Thyroid cancer occurs three times more frequently in women than in men. Thyroid cancer originates from one of two different types of thyroid cells: follicular cells or so-called parafollicular, or C cells.
