Thyroid cysts are fluid-filled sacs that can develop in the thyroid gland. The thyroid gland is a small organ in the neck that secretes hormones that regulate the speed of chemical processes in the body (known as the metabolic rate). Thyroid cysts, a type of thyroid nodule or lump, are usually fairly small, ranging in size from less than a third of an inch across to an inch across, or larger in rare cases. The fluid-filled cysts are usually benign or noncancerous, but occasionally they contain solid material in addition to the fluid, and this may be cause for concern.
