good news/bad news

The results of the PET scan show that the lesions in Mitchell's liver are just about gone! Great news. Unfortunately the lesion/nodule in his lung is hanging in there...It is about 3 mm larger than the first PET. Granted 3 mm is so small, it's almost nothing, right? Also there is a decent reason to believe that the nodules in his lung are becoming cavitious. I'm keeping my fingers crossed. Basically, Mitchell will have to continue chemotherapy for the next 3 to 4 months. At the end of that time, there will be another PET to determine what will happen next. It still seems sketchy, but I'm learning to live with it.
