How to treat adrenal tumors depends on whether they have endocrine function abnormalities. Tumors without endocrine abnormalities can be followed up and observed first. Tumors with obvious endocrine abnormalities can be treated by surgery and medication. Adrenal tumors can be divided into non-functional tumors and functional tumors according to whether they have endocrine function or not. Non-functional tumors are usually found during physical examination or tests unrelated to adrenal diseases because they do not have endocrine abnormalities, and can be followed up and observed first because they have no clinical symptoms. Functional tumor will make the level of certain hormones in the body higher than normal. The site occupied by the tumor and the nature of the tumor can be clarified through symptoms and blood tests, CT, MRI and other examinations. For adrenal tumor, surgery is the key. Only by removing the tumor tissue can the body hormone return to the normal range, and the common surgical method is laparoscopic adrenal adenoma removal surgery. If the tumor is too large, it can also be removed using open surgery. Medications may be required before and after surgery depending on the circumstances. If the patient is not suitable for surgery, medication may be used.
