Is the right adrenal nodule serious?

The right adrenal nodules are generally not serious. Most of the adrenal nodules are benign under normal circumstances according to the size of the nodules. Adrenal nodules below 4cm can be observed regularly and followed up normally, and do not need special treatment. Adrenal nodules over 4cm must be treated surgically. In addition, from a functional point of view, most adrenal nodules are non-functional adenomas, which require regular follow-up and do not require medication or surgery, while functional adrenal nodules require medical or surgical treatment. Common diseases include primary aldosteronism, pheochromocytoma, and adrenal cortical diseases, which are further diagnosed according to blood tests related to adrenal function. In rare cases, there are adrenal metastases and adrenocortical carcinoma, which are malignant and often require comprehensive diagnosis and treatment based on the patient's medical history.
