Current scientific theories, such as the "delayed infection" hypothesis , suggest leukemia may be a two-step process: a genetic "hit" occurs in utero (potentially triggered by maternal inflammation), followed by a second "hit" from common infections in early childhood. such as brain tumors or lymphoma
