Thyroid nodules
Palpable thyroid nodules affect 4-7% of the adult population with female predominance, although it has been predicted that between 40-70% of adults may have clinically undetected nodules only identifiable by ultrasound or autopsy. The vast majority of these nodules are benign, with only 5-10% proving malignant. Clearly therefore surgical excision of all palpable or incidentally detected thyroid nodules would result in large numbers of individuals unnecessarily being exposed to the risks of surgery.
