Adrenal cortical 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 frequently found among middle aged and elderly people.

   The average age of patients is around 45 to 50, but adrenal cortical cancer can occur at any age; even in children. It also seems to occur more often in females.
