Kidney Cancer – Beatriz’s Story – Valley Children’s When Beatriz was 13 months old, she was diagnosed with Wilms’ tumor, a rare kidney cancer that makes up about 6 percent of all childhood cancers. After Valley Children’s pediatric surgeons removed the mass, she began a comprehensive, five-month treatment plan of chemotherapy and radiation to kill any remaining cancerous tumor cells. Beatriz is one of more than 120 children diagnosed with cancer each year in this region. To learn more about Valley Children’s Cancer and Blood Diseases Center, please visit Valley Children’s.
