That's great news, and encouraging in that it appears the chemo is shrinking the tunor. Once Pat was able to start swallowing food again, things improved steadily. It got a bit more difficult as we progressed through the radiation because then it was a different sort of discomfort swallowing but that was very short lived. So happy you are moving in a forward direction. Thanks for info on CEA markers. Your Dad must he feeling more hopeful with the turn in events.
