The most important aim of the World Cancer Day campaign is to help the early diagnosis of childhood cancer. The earlier this disease gets diagnosed, the higher will be the survival chance. Wilm's tumor is one of the common childhood cancers. Do refer to a physician when you notice one of these symptoms in a child around you: a large lump or hard mass in child’s belly; blood in the urine; high blood pressure; shortness of breath; fever that won’t go away. Keep in mind that these symptoms do not necessarily mean that a child has cancer; however, refer to a doctor as soon as you notice any of them. Early diagnosis is the key to early treatment for this disease.
