Thyroid Cancer

Thyroid cancer begins in the thyroid gland, which is situated just below the Adam’s apple and is responsible for secreting hormones that regulate growth and development. Cancer can begin in either of the thyroid’s two main types of cells, follicular cells or parafollicular cells (C cells). About 9 out of 10 thyroid cancers begin in the follicular cells.
