The lymph node biopsy came back negative. The radiologist who did the biopsy said he could not see any enlarged nodes on the ultrasound (MRI showed enlarged nodes of 1.5 to 2cm three days prior). He had another radiologist come in and look and he didn't see any either. He ended up only sampling one node under my jaw on the right side. That is the one that came back clean. After much discussion, we decided to only have the tongue resection on Monday. We will then make the decision on END based upon the pathology report from that surgery and a PET/CT. My tumor measures 1.5 cm, but the surgeon can't tell how much of that is scar tissue from a prior surgery to remove precancerous lesions. So we will know more about actual size and depth after it has been fully excised. I also plan to get another second opinion at UCSF prior to deciding. Thanks again for all the input. I'm sure I'll have many more questions as we move through this process.
