Exams and Tests
The first step in diagnosing thyroid nodules is a medical history and physical exam. Thyroid nodules often are found during a physical exam or during a CT scan or ultrasound of the neck, chest, or head done for another problem. Most people do not find thyroid nodules on their own, because they are difficult to feel and usually do not cause symptoms.
If your doctor finds a thyroid nodule, he or she may refer you to an endocrinologist for more tests and treatment.
Common tests for people with thyroid nodules are:
Other tests you may have include:
If your nodule is not cancerous, your doctor will see you regularly to monitor the size of your nodule. He or she may do other tests, such as checking your thyroid-stimulating hormone (TSH) levels or doing a thyroid ultrasound. If your nodule grows, other tests or surgery may be needed.
If your thyroid gland was removed because of cancer, your doctor may test for thyroglobulin, a protein made by both normal and cancerous cells. High levels of thyroglobulin may mean that the cancer has spread (metastasized) to other parts of your body.
