How is thyroid cancer diagnosed?
A number of tests may be performed to investigate symptoms of thyroid cancer and confirm a diagnosis. Some of the more common tests include:
- a physical examination and patient history
- examination of a blood sample
- imaging of the thyroid, which may include ultrasound, computed tomography (CT) scan or magnetic resonance imaging (MRI)
- internal examination of the voicebox using a laryngoscope – a thin tube with a light on the end of it
- taking a sample of tissue (biopsy) from the thyroid gland for examination under a microscope.
There are a number of conditions that may cause these symptoms, not just thyroid cancer. If any of these symptoms are experienced, it is important that they are discussed with a doctor.
