Childhood cancer refers to a group of cancers that occur in children, typically defined as individuals aged 0 to 19 years. This category encompasses various types of malignancies that are distinct from adult cancers due to differences in biological behavior, treatment responsiveness, and overall prognosis. Common types of childhood cancers include leukemia, brain tumors, neuroblastoma, Wilms tumor, and lymphoma.
The incidence of childhood cancer is relatively low compared to cancer in adults, but it remains a leading cause of death by disease in children. Diagnosis often involves a combination of imaging studies, biopsies, and blood tests, and treatment may include chemotherapy, radiation therapy, surgery, or targeted therapies, depending on the specific type and stage of cancer.
Research into childhood cancer focuses on understanding its causes, improving treatment approaches, and enhancing survivorship outcomes. Early detection and advancements in medical science have significantly increased the survival rates for many childhood cancers, leading to greater emphasis on long-term health and quality of life for survivors.
