Katie was successfully treated for Wilms’ tumor, a malignant kidney tumor, and thyroid cancer. She was diagnosed with Wilms’ tumor just before her 4th birthday. She had blood in her urine and had been out of sorts. Her parents took her to the pediatrician, who could feel something in her abdomen. The tumor was stage 4 when she was diagnosed and she had surgery to remove the tumor on her 4th birthday. Dr. Diller understands not only the medical side of cancer, but also the interpersonal side and how it affects kids physically and mentally.
