Hello. My friend's six year old daughter, Ella was recently diagnosed with Stage 4 Ewing's Sarcoma with the primary tumor in her left humerus. It has metastasized to her lungs. They live in Tucson, Az and Ella is currently undergoing chemo at the University of Arizona. She is in a trial. They are looking for a different hospital that both specializes in Sarcoma and has a pediatric oncology unit. Where they are now is neither. Ella is very bored and lonely and her parents want her to be around other kids so that she can have some social time as well as some emotional support from other kids who are fighting cancer. Is there such a hospital? They want the very best for their daughter, as all parents do and hope to find it all in one place. Can anyone suggest a top notch pediatric cancer hospital, hopefully one that specializes in Sarcoma? Thank you in advance.
