We took him to the Marsden where we met Kathy Prichard-Jones, she is the professor of pediatric oncology and happens to run a large team of researchers who research Wilms tumors. Wilms tumors have been “curable” for 20 years or so and 90% of children apparently make a full recovery. The treatment is chemotherapy for a few weeks, followed by surgery to remove the kidney and growth followed by more chemotherapy. He would need to have a biopsy and a CT scan to confirm that it is Wilms tumor and that it hasn’t spread anywhere else (unlikely from the fact that he is acting happy).
