Final answer:
Leukemia is the most prevalent type of cancer in children, and early treatment often leads to remission. Survival rates have improved over recent decades for pediatric cancer.
Step-by-step explanation:
Among the statements provided, it is true that leukemia is the most prevalent type of cancer in children, specifically in middle childhood. Leukemia, which is the production of abnormal white blood cells most commonly in the bone marrow, accounts for approximately one-third of all childhood cancers. Treatment options are available, and early treatment of leukemia can potentially lead to remission. Contrary to the notion that childhood cancer incidence has decreased dramatically or that children with cancer are dying earlier, advancements in medical treatment have led to an increase in survival rates over recent decades. The claim that one in every 130 children in the US develops cancer by the age of 17 is an assertion that requires specific epidemiological data to substantiate.
