What Is Thyroid Cancer? Health Article

In order to understand what is happening when you have cancer, it helps to know how your body works normally. Tiny building blocks called cells make up your body. Normal cells grow and multiply when your body needs them. These cells can die out when your body does not need them. Cancer may occur when abnormal cells grow whether your body needs them or not.

Thyroid cancer is an uncommon cancer that begins in the thyroid gland. The thyroid gland is in your neck. It is located under your Adam’s apple and above your collarbone. You usually cannot see or feel your thyroid. It faces the front, but it’s under the skin. It’s shaped like a butterfly, with 2 lobes (a right and left lobe) connected by a bridge of tissue, called the isthmus. The thyroid is made up of 2 main types of cells. The follicular cells make and store hormones. The C cells make the hormone calcitonin.
