The incidence rate of adrenal tumors is less than 0.5%, which is not a common tumor in clinic, among which the number of patients with benign adrenal tumors is relatively higher than that of malignant adrenal tumors. The incidence of adrenal tumors is higher in female population, and the main clinical manifestations are centripetal obesity, hypokalemia, diabetic tendency, periodic paralysis, and headache, palpitation, etc. Some patients may also suffer from persistent high blood pressure, low blood pressure, or normal blood pressure, and the fluctuation range of the blood pressure is generally larger, so the patients may suffer from severe headache. Compared with abdominal tumors, the prevalence of malignant adrenal tumors is not high, and many patients’ malignant adrenal tumors are metastasized from other tumors in the body. Benign adrenal tumors, on the other hand, are more common. The causes of adrenal tumors are directly related to tobacco and alcohol stimulation, bad dietary habits, human hormone metabolism, chromosomal abnormalities and genetic factors. Patients should quit smoking and drinking, develop good dietary habits and cooperate with doctors to receive treatment.
