New study sheds light on the progression and management of ‘silent’ adrenal tumours

CT scans are increasingly performed for a variety of medical indications, including for general health screening, which is growing in popularity. An estimated 4% of CT scans will coincidentally uncover a tumour in the adrenal gland, with no associated clinical symptoms. However, until now, evidence on how to manage these ‘silent’ tumours has been lacking, despite the fact that the growing demand for CT scans is likely to lead to increasing numbers of detections.
