The removal of adrenal adenomas is not only related to the size of the tumor, but also to the type of disease and cannot be generalized. Adrenal adenomas are tumors of the adrenal cortex, which are clinically divided into non-functional adrenal adenomas and functional adrenal adenomas. 1. Non-functional adrenal adenoma: often found through routine physical examination, usually small in size, regular review is recommended, if the adenoma is larger than 3cm, surgical resection is needed. 2. Functional adrenal adenomas: regardless of the size of the adenomas, timely surgical resection is required, such as laparoscopic surgery. Functional adrenal adenomas are generally categorized into cortisolism, primary aldosteronism, pheochromocytoma, etc., which usually tend to cause hypertension, hypokalemia, biochemical electrolyte abnormality, etc., which are more harmful to human body, so they need to be operated as early as possible. Patients with adrenal adenoma should take into account the development of their own condition and follow the doctor’s instructions for regular review or early surgical treatment, so as to avoid delaying the treatment and leading to serious condition.
