These hormones regulate heart rate, blood pressure, and many other vital functions, including response to stress and infection. The adrenal cortex is the outside layer of the 2 adrenal glands.Cancers of the adrenal cortex are rare. The majority of these tumors produce excess hormones. The excess hormones can change hormonal balance.
