NOPHO, The Nordic Society of Paediatric Haematology and Oncology was founded in the early 1980s by a group of enthusiastic friends with the ultimate goal to increase survival for children with cancer. Over the years, NOPHO has grown into a big family that now includes physicians, nurses and researchers from the Nordic and Baltic countries, with increasing collaboration with other international groups such as I-BFM, ITCC, PaeNNO, SIOP, and SIOP Europe.
