Can you tell me what it mean when the doctor's find a 9mm nodule on your adrenal gland?

Incidentaloma: This was undoubtedly found on a ct or MRI that was done for some other reason. These incidentally discovered "incidentalomas" are usually benign lumps and of no significance. There are 2 questions your doctor will want to ask: 1. Is the nodule secreting any hormones, like adrenaline, cortisol, etc; and 2. Is the nodule growing, which would raise a suspicion for cancer.
