Thyroid carcinoma is a cancer that occurs in the thyroid, a butterfly-shaped gland that is located in the neck, just below the Adam's apple. The thyroid gland makes and stores hormones that regulate growth and development in childhood. Hormones made in the thyroid gland also regulate metabolism (the rate at which food is converted to energy) body temperature, blood pressure, heart rate, and affect the muscles, the nervous system and other organs.
Thryoid carcinoma occurs when cells in the gland become abnormal and grow out of control. Thyroid cancer can also metastacize (spread) to other parts of the body. Although thyroid carcinoma can occur at any age, it is usually found in young people ages 15 to 19.
