How do I know if I have a thyroid nodule?
A thyroid that is enlarged or pushed off to one side could be a sign of a tumor. Nodules absorb more or less iodine and this will make them look darker or lighter on the scan. A nodule is usually lighter if it has not taken up the iodine (often called a 'cold' nodule). If part of the thyroid appears lighter, it could be a thyroid problem.
