Welcome to The National Children’s Cancer Society’s Late Effects Assessment Tool. Here you can learn about the long-term medical impact of your specific diagnosis and treatment. The more information you know about your cancer treatment and the possible long-term effects, the better prepared you will be to meet any challenges the future may bring. 

The information for the Late Effects Assessment Tool was completed in collaboration with Robert Hayashi, MD – Associate Professor of Pediatrics, Division Hematology/Oncology, Washington University School of Medicine; Director of Hematology/Oncology St. Louis Children’s Hospital.
