Adrenal Cancer

Adrenocortical carcinoma, or ACC, is a cancer of the adrenal glands, which are two small triangular-shaped glands that sit on top of each kidney. The outside of these glands is called the adrenal cortex. The adrenal cortex makes important hormones that help your body control water balance, blood pressure, stress response, and cause the body to have male or female traits. ACCs form in the adrenal cortex.

An ACC may be functioning, which means it makes more hormone than normal, or non-functioning, which means it has no effect on hormone production. A functioning ACC tumor often makes too much of the hormones cortisol, aldosterone, testosterone, or estrogen.
