What are the key statistics about adrenal cancer?

Adrenal carcinomas are very rare and the real number diagnosed in the United States is not known. It is probably around 300 per year. They are much less common than adrenal adenomas, which are found frequently 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 45 to 50, but adrenal cortical cancer can occur in people of any age; even in children. It also seems to occur slightly more often in females.
