Thyroid nodules:


Thyroid Nodules are defined as solidified masses of tissues that appear as distinct lumps on the thyroid gland. They can be differentiated from the thyroid parenchyma through ultrasound techniques. These are formed when the rate of cell formation in the thyroid gland is abnormally higher than the rate of cell death. The abnormal growth of these cells is attributed to multiple etiological factors. The excess cells combine to form lesions on the thyroid gland. These nodules can be benign or malignant according to the nature of the constituent cells. Both categories of nodules can cause suppression or overstimulation of the thyroid gland. Benign nodules of the thyroid gland are not very harmful and need not be treated unless recommended by a doctor. But malignant thyroid nodules are detrimental to health and can even cause death.
