Adenomas of the adrenal gland are non-cancerous (benign) tumors on the adrenal gland. Most do not cause any signs or symptoms and rarely require treatment. However, some may become “active” or “functioning” which means they produce hormones, often in excess of what the adrenal glands typically produce. High levels of these hormones can lead to complications, including primary aldosteronism, Cushing’s syndrome and other medical conditions. Functioning adrenal adenomas may be treated with surgery and/or medications.
