The cause of most pheochromocytomas is not known. A small minority (about 10-20%) of pheochromocytomas arise because a person has an inherited susceptibility to them.
Because pheochromocytomas arise from chromaffin cells, they are occasionally called chromaffin tumors.
Pheochromocytomas are rare tumors. They have been reported in babies as young as five days old as well as adults 92 years old. Although they can be found at any time during life, they usually occur in adults between 30 and 40 years of age.
If a pheochromocytoma is suspected, urine and/or a blood test are usually recommended. A test called "24-hour urinary catacholamines and metanephrines" will be done.
Most (90%) are benign tumors so they do not spread to other parts of the body. However, these tumors can cause many problems and if they are not treated and can result in death.
Multiple Endocrine Neoplasia, type 2A (MEN2A), Multiple Endocrine Neoplasia, type 2B (MEN2B), von Hippel-Lindau disease (VHL) and Neurofibromatosis type 1 (NF1).
For localized pheochromocytomas the 5-year survival rate is 95%. This rate decreases with aggressive tumors that have metastasized. The prognosis for adrenal cortical cancer is not as good with a 5-year survival rate of 10-35%
A pheochromocytoma is a rare type of tumor that develops in the adrenal medulla, which is located in the adrenal glands on top of each kidney. It causes an overproduction of hormone-like substances, including adrenaline and noradrenaline, which can lead to symptoms like high blood pressure, rapid heart rate, and sweating.
Very few people are affected by cancers of the heart - the myocardium doesn't divide very much past adolescence, so the risk of myocardial cancer is very low. The pericardium and endocardium do divide throughout adulthood, but the incidence of cancer from these tissues is also quite low. However, there are a couple of cancers that can metastasize to the heart, including lymphoma and pheochromocytomas.
