Childhood B cell leukemia: Intercepting the paths to progression.

B-cell Acute Lymphoblastic Leukemia (B-ALL) is the most common pediatric cancer, arising most often in children aged 2-5 years. This distinctive age distribution hints at an association between B-ALL development and disrupted immune system function during a susceptible period during childhood, possibly triggered by early exposure to infection. While cure rates for childhood B-ALL surpass 90% in high-income nations, survivors suffer from diminished quality of life due to the side effects of treatment. Consequently, understanding the origins and evolution of B-ALL, and how to prevent this prevalent childhood cancer, is paramount to alleviate this substantial health burden. This article provides an overview of our current understanding of the etiology of childhood B-ALL and explores how this knowledge can inform preventive strategies.
