“May all be happy, may all be healed, may all be at peace and may no one ever suffer."
Pheochromocytoma is a rare type of tumor that arises from cells called chromaffin cells, which are located in the adrenal glands or in the sympathetic ganglia of the nervous system. The tumor produces excessive amounts of catecholamines, such as epinephrine and norepinephrine, which can cause high blood pressure and other symptoms.
Symptoms of pheochromocytoma can include:
Diagnosis of pheochromocytoma usually involves blood and urine tests to measure levels of catecholamines and their breakdown products. Imaging tests, such as CT scans or MRI, may also be used to locate the tumor.
Treatment for pheochromocytoma typically involves surgery to remove the tumor. Before surgery, medications may be given to control blood pressure and prevent complications such as heart attack or stroke. In some cases, radiation therapy or chemotherapy may be used to shrink the tumor before surgery.
If left untreated, pheochromocytoma can lead to complications such as heart failure, stroke, or kidney damage. Therefore, it is important to seek medical attention if you experience any symptoms suggestive of pheochromocytoma.
