Although many thyroid nodules can be felt by the patient or by a doctor during physical examination, more and more nodules are being discovered incidentally during an imaging test (like carotid USG or CAT scan) being done for another reason.

Nodules in the thyroid are usually found during a physical exam by the doctor. Occasionally the patient will notice the nodule and bring it to the attention of their physician. Other times, the nodules can be seen on an ultrasound or other imaging study.The nodules are often found when the physician suspects a thyroid disorder and is doing an examination specifically to assist in making a diagnosis.
