If the pheochromocytoma is benign, it can be surgically removed and usually does not affect the patient’s life expectancy. Pheochromocytomas are tumors that originate in the chromophobic tissue of the neuroectoderm and can lead to increased secretion of catecholamines in the body, which in turn can lead to increased blood pressure in patients. Pheochromocytoma may also lead to hypotension, hypoglycemic shock, and can have adverse effects on the heart. Pheochromocytoma is treated with medication and surgical removal. In the case of benign pheochromocytomas, surgical removal usually does not affect the patient’s life expectancy. In the case of malignant pheochromocytoma that has metastasized, severe cases can die within a few months, and a few can survive for more than 10 years, with a 5-year survival rate of about 45%. Since pheochromocytoma is multiple and recurrent in nature, patients need to be reviewed regularly so that any abnormalities can be dealt with promptly.
