Pediatric oncology is a specialized branch of medicine that focuses on the diagnosis and treatment of cancer in children. This field deals with a wide range of childhood cancers, including leukemia, brain tumors, lymphoma, and other types of cancer that can affect young patients. Pediatric oncologists work closely with a multidisciplinary team of healthcare professionals to provide comprehensive care for children with cancer, including chemotherapy, surgery, radiation therapy, and supportive care. Research in pediatric oncology aims to improve treatments, outcomes, and quality of life for children with cancer, as well as to understand the underlying causes and genetic factors that contribute to the development of childhood cancer.
