Once a diagnosis of pheochromocytoma is made, it needs to be determined whether it is benign or malignant. If it is benign, surgical means can be used to remove it; about 10% are malignant, and if it is malignant, radiation therapy or chemotherapy can be considered to eliminate and relieve it. For people with high urinary catecholamine levels, nine times out of ten, they have pheochromocytoma. This is due to the fact that pheochromocytoma secretes adrenaline, which leads to high blood pressure and even endocrine metabolic disorders, reflected in rising blood and urine catecholamine levels. Therefore, blood pressure should be controlled with antihypertensive drugs during treatment. Currently, alpha-blockers such as phenobenzyme, prazosin and doxazosin are used clinically, and beta-blockers can be added if the patient is tachycardic. Alpha-blockers must be used to lower blood pressure before using beta-blockers, and they should be used continuously before surgery. Laparoscopic surgery is usually used clinically, and this method is more mature in China. If the pheochromocytoma is attached to the internal organs and the attachment is deep, all the organs need to be removed, otherwise it may recur, and in case of malignant tumor, it may also metastasize. Pheochromocytoma can seriously affect blood pressure, and will constantly secrete adrenaline, which can easily cause rapid heart rate and emotional excitement, so it is important to pay attention to physical examination and balance the mind in daily life.
