Welcome to SIOP

SIOP, the International Society of Paediatric Oncology, is a dynamic and vibrant global organisation dedicated to increasing knowledge about all aspects of childhood cancer. Our aim is to improve and optimise treatments throughout the world. SIOP’s vision is that no child should die of cancer.

We encourage all healthcare professionals involved in work on cancer in children and young adults to join SIOP, attend our congresses and regional meetings, and use SIOP as a means of developing their networks.
