The Swiss Children's Cancer Aid was founded in 1987 under the name "interest group for children with cancer". Since then, the association has been supporting affected families and providing financial, advisory, informative and many activities.

The research projects focus on curing the most serious forms of cancer in children and adolescents. The children's cancer research is part of the Research Center for Children (FZK) at the Children's Hospital Zurich.
