Pheochromocytomas develop in the small glands on top of the kidneys (adrenal glands). They most commonly affect people between the ages of 20 and 50 but can occur at any age.
Symptoms include sweating, rapid heartbeat, and severe headache.
Untreated, the condition can severely damage the cardiovascular system. Surgical treatment to remove the tumor usually helps control blood pressure.
