This woman has quite the legacy. Thank you Dr. Evans. 

Dr. Evans was a renowned figure in the world of childhood cancer. In 1971 she developed what has become known as the Evans Staging System, a protocol for assessing patients with neuroblastoma, a childhood cancer that involves nerve cells. The system helps determine which children need aggressive treatments and which could be aided with less invasive methods.

“More than any other person during the last three decades,” a 2000 article in a cancer journal said of her, “she has transformed our thinking about neuroblastoma.”
