Jeanne: Thank you for the information. So far, the vet did another radiograph, and found 2 more enlarged masses in his chest. They could either be enlarged lymph nodes or 2 fat masses. Marshall is home with me now. He is going into surgery Monday to remove the largest mass by his butt. I am hoping all goes well. Thanks again- Vanessa & Marshall [log in to unmask] [Posted in FML issue 1503]
