Children with WAGR syndrome have a 50% risk for developing Wilms tumor before the age of 3. Caroline had this cancer when she was only 18 months old. As kids with WAGR syndrome grow up, the risk may continue: Amy was 19 years old when her cancer returned. More research is the key to better, more effective treatment. You can help make this happen! You can join our team of walkers - we're *virtual* so you can walk anywhere, anytime, any distance -  or you can make a donation to show your support. Then check in throughout September to log your miles, upload photos, or see our progress. We're going to Walk Around the World for WAGR, and we'd love to have you with us!
