They’d like to raise 2,500 euros that will directly go to the Translational Research in Child Cancer group, led by Dr. Josep Sánchez de Toledo at VHIR.The athletes are from León, Valencia and the Canary Islands, they have participated in several Ironman, but they have never visited the Pediatric Oncology Unit at Vall d’Hebron University Hospital. However, they are convinced that they want to contribute to help the weakest and reach the 0 mortality rate in child cancer.The research group at VHIR is dedicated to investigate new treatments and diagnosis methods to combat cancer during childhood. The survival rate to this disease is high, close to the 80%, but some neoplasias show lower rates. In this sense, further research is needed in order to find new therapies that could improve the general prognosis and the survival high-risk patients.
