The thyroid and types of thyroid cancer
The thyroid is a small gland in the front of the neck just below the voice box (larynx). It is made up of two parts, or lobes. It's one of a network of glands throughout the body that make up the endocrine system. This system is responsible for producing the body’s hormones that help to control and influence various functions.
