Thyroid Gland

Thyroid gland is a very important gland in the body which is located in the lower part of the neck, right above the sternum. This gland produces hormones that are vital to our well being. There are two kinds of cells in thyroid gland. Follicular cells, which produce thyroid hormones, that are essential for growth and development of all body tissues, and Parafolicullar cells which produce Calcitonin; a hormone that controls calcium levels in blood.

Thyroid nodule, refers to any solid lump in the thyroid gland. Most these nodules are benign and do not contain any cancer within them. However, any lump in the thyroid gland has to be studied properly to make certain of its nature.
