The thyroid gland is situated in the front of the neck. Thyroid nodules are common and affect more women than men. Thyroid nodules can be solitary but can be multiple in a condition called multinodular goiter (MNG).
A patient with thyroid nodules or swelling should have a thorough assessment. About 5% of nodules may contain cancer. However if detected early, the prognosis is good. Large nodules may cause obstructive symptoms like swallowing difficulties or breathing problems.
An ultrasound, blood test and a needle test of the thyroid nodule may be performed to aid in the diagnosis.
