A pheochromocytoma is an adrenal gland tumor that secretes epinephrine and norepinephrine hormones. These hormones are responsible for regulating heart rate and blood pressure, among other functions. Pheochromocytomas occur most frequently in young to middle-aged adults between the ages of 30 and 60. Ten percent of individuals affected are children who usually develop symptoms between the ages of 6 and 14.
The causes of pheochromocytoma are multifactorial, meaning many factors contribute to the cause of the condition. In most cases, both genetic and environmental factors play a role. About 25 percent of cases are part of a hereditary syndrome.
