I have always had adrenal gland issues and have never had a tumor! By disorder, she simply could have meant an issue! Adrenal gland issues are fixable, so try not to worry too much!! I did urinate very frequently, even if I wasn't drinking much. Does your daughter have trouble with energy, or feeling wiped out? This can can go hand in hand with adrenal glad issues. Many adrenal gland problems can be listed as "genetic" in the symptoms. Right next to "tumors" and "cancer." You see, there are many causes and most actually have nothing to do with tumors. Adrenal gland problems do need to be treated immediately, but the good news it it's not usually complicated or difficult. Good luck!
