Study investigates the prevalence of adrenal tumors in an unselected screening population

A cross-sectional study of more than 25,000 adults has found that with increased screening, the prevalence of adrenal tumors in an unselected community population was 1.4%. The prevalence increased with age, from 0.2% in adults aged 18 to 25 up to 3.2% in adults older than 65 years of age. However, approximately 70% of identified tumors were nonfunctioning, meaning they did not make extra hormones, regardless of the participant’s age. The findings are published in Annals of Internal Medicine.
