Just off the phone with the vet. Sebastian has some minor right adrenal gland changes, none in the left. He has a cyst in his right kidney, vet says these are usually benign but that kidney disease is a possibility that we will have to watch for. He has no liver changes, his heart is good and his large spleen is just normal for him. There is no cancer!! The vet will look into surgery and let us know later this week.
