About adrenal cancer

Adrenal cancer is rare, affecting between 300 and 500 people in the United States annually, according to the American Society of Clinical Oncology. However, adrenal tumors are found in about one in every 10 people who have an imaging test of the adrenal gland. The majority of these tumors are noncancerous (benign).

Adrenal cancer is diagnosed when abnormal cells develop in or travel to the adrenal glands—tiny glands above the kidneys. The disease is most often discovered as a tumor in the glands’ outer layer, known as the adrenal cortex, which produces steroids, such as cortisol and aldosterone, and helps the body manage stress and regulate blood pressure.
