Adrenal carcinomas are very rare and the real number diagnosed in the United States is not known. It is probably around 200 per year. They are much less common than benign adrenal tumors (adenomas), which are found fairly often among middle aged and elderly people. Adrenal tumors (most of which are adenomas) are found in about one in every 10 people who have an imaging test (like a CT or MRI) of the adrenal gland.
The average age of patients with adrenal cancer is around 46, but adrenal cortical cancer can occur in people of any age; even in children.
