Welcome to SIOP

SIOP is the major global organisation concerned with the issues of children and young people who have cancer.
For the past 35 years it has brought together doctors of many different disciplines to develop better care for this disease.

In recent years nurses have become involved and over the past years we have been developing an alliance with parents and their complementary organisation ICCCPO.
Our mission is to bring the best possible care for children with cancer to the farthest corners of the globe. It is currently a minority of sufferers who have access to the incredible advances which have been made over the lifetime of SIOP. When we started, 75% of children with cancer died. Now, with the best treatment 75% can be cured. However, there are many parts of the world where few, if any, children have access to the best, or even limited treatment.

SIOP aims to bring together all of those concerned with the care of children with cancer and we hope that you will find information on this website which will be of help to you!
