According to the National Cancer Institute, adrenal carcinoma is a rare form of cancer in which malignant cells form on the outer layer of the adrenal gland. The most common symptom is severe pain in the abdomen.

The adrenal glands are two small glands that sit on top of your kidneys, and each one of your kidneys has one of these glands.

The adrenal glands normally release important hormones that help regulate blood pressure, balance the water and salt in the body, and cause the body to have masculine or feminine characteristics.

Having certain genetic conditions can increase a person's risk of adrenal carcinoma, including Li-Fraumeni syndrome, Beckwith-Wiedemann syndrome, and Carney complex.
