1. However, a study from 2007 has reported an increased cancer incidence after radioiodine treatment for hyperthyroidism.

2. Avoidance of reoperations and optimal conditions for effective postoperative radioiodine therapy are arguments for this aggressive strategy.

3. Radioiodine exposure can result in both deterministic effects (hypothyroidism and acute thyroiditis) and stochastic effects (thyroid cancer and benign thyroid nodules).

4. Anaplastic and undifferentiated thyroid carcinoma as well as differentiated thyroid carcinoma (DTC) not cured by combination surgery and radioiodine ablation are candidates for palliative chemotherapy.
