In fact, adrenal tumor is only a hormone-secreting organ near the kidney, and adrenal tumor is not directly related to the kidney, and most of the adrenal tumors are benign, so don’t worry too much. So once adrenal tumors are found, should they be cut out? In fact, if these tumors are small in size and do not affect the hormone secretion function, and the blood pressure, blood potassium and weight are normal or stable, then it is not necessary to remove them at all, as long as regular physical examination and monitoring of its changes are performed every year or two years. If you suspect that these tumors have secretory function, you should go to the endocrinology or urology department of the hospital for relevant examinations, such as laboratory tests of hormone concentration in blood or urine, experimental drug treatment, etc., which can explore the tumor function more clearly. In the following two cases, surgery should be performed as soon as possible: ① Tumor grows gradually and the diameter measurement exceeds 4 cm. ② The tumor affects the endocrine function, and the patient shows a sharp rise in blood pressure, frequent decrease in blood potassium, or very severe cortisolism, such as a relatively rapid onset of significant centripetal obesity, round facial fat (“full moon face”), fatty back of shoulder (“buffalo back “), lower abdominal and axillary skin fissures, increased female beard as well as menopause, abnormal blood sugar and severe osteoporosis should be treated surgically as soon as possible, regardless of the size of the tumor. The vast majority of adrenal tumors, even a portion of malignant adrenocortical carcinoma, can be cured by surgery.
