We're at the VA and dealing with two different facilities as the one closest to us did the rad/chemo and the one in LA has the surgical center. The surgeon did tell me that they thought they had gotten everything with the surgery (were able to get clear margins) and this is just precautionary, if it's availabe to use it! But they haven't done any tests at all since the surgery, really haven't even looked at him closly so it's weird that this is happening this way? They've also referred us to chemo to see if those dr's want to do additional treatment...we'll see if there's any further explanation today (although the Rad Dr we see is very haughty and not too keen on conversation!)
