Who is a good candidate for this therapy?

Good candidates include patients with hyperthyroidism (e.g., Graves' disease) that has not responded to medication, or those with differentiated thyroid cancer after surgical removal of the thyroid. Contraindications include pregnancy, breastfeeding, and severe thyroid eye disease, as the therapy can worsen eye symptoms. A thorough evaluation by an endocrinologist, including blood tests and a thyroid scan, is required to confirm suitability.
