It grew a bit more to 8cm. The dr said that the most common place it would move to is the lungs and the lungs are clear. The doctor basically said that he doesn't think that at 83 years old that my father will end up having to deal with this destroying his kidney (unless he lived to 105). He said if he was 50 or 60, he would suggest surgery. My father is feeling fatigue, no appetite, and has lost weight but we think he also has a uti (waiting on the urine culture). Hoping that is from the UTI because he said that the kidney function is stable at 1.4 and GFR is 50 so anything he is feeling isn't from the kidney or tumor. The MRI also checked and the pancreas, spleen, and liver are all clean.
