A nodule is an area of tissue within the thyroid. Finding one does not mean that you have cancer. The next step usually involves reviewing the ultrasound, your medical history and your thyroid function.

Bring your ultrasound report and images. Ask whether you need a biopsy or monitoring. A normal TSH result cannot, by itself, establish whether a nodule is benign.

Questions for your appointment
