Thyroid nodule

Masses in thyroid gland
Thyroid nodules are lumps which commonly arise within an otherwise normal thyroid gland. They are often located at the edge of the thyroid gland so they can be felt or even seen as a lump in the throat. Usually benign tissue growths, or cysts which are filled with fluid, occasionally thyroid nodules can take on characteristics of malignancy and require surgical excision.
As many as 50% of a population will have a nodule somewhere in their thyroid. One in 12 to 15 women has a thyroid nodule; One in 40 to 50 men has a thyroid nodule; More than 90 percent of all thyroid nodules are benign (non-cancerous growths).
