We got Kol's MRI results on Monday. In the doctor's words, there was "essentially" no difference between this scan and the last one in terms of the tumor, which is relatively good news. However, the radiologist says that there may - MAY - be a new tiny nodule in the surgical site. The oncologist says that it's nothing to worry about (yet), but that it will be watched closely at his next scheduled scan three months from now.
We've had a couple days to process this now. I don't think I handled the news particularly well to begin with - it definitely wasn't what we were hoping to hear - but now I feel like I am able to keep calm and carry on. Kol handled the news with typical aplomb - he's quite convinced that it's just the MRI equivalent of a speck of dust on the camera lens. Kristen had some tears, but is quite optimistic, and the girls seemed to take the news in stride. I think we're going to be OK.
Thank you all for your prayers and your encouragement.
