Yes, it can look normal and still over produce the hormones, or it may be larger now (than it was 6 weeks ago) and is now starting to overproduce the hormones. Thus it is either time to run the Tenn panel to see if his hormone levels are elevated or do a second surgery. Hope that helps, Jerry Murray, DVM [Posted in FML issue 4087]
