Pediatric cancers are diseases where abnormal cells grow uncontrollably in kids' bodies. These cancers are different from those in adults and can occur in various areas like the blood, bones, or organs. Common types include leukemia, brain tumors, and neuroblastoma. Children with cancer may experience symptoms like pain, fatigue, or changes in weight. Doctors use special tests to diagnose and decide the best treatment, which may involve surgery, chemotherapy, or radiation. Supportive care is crucial to help children cope with side effects. Although it's a challenging journey, many kids overcome pediatric cancers with the support of medical teams and their families.
