Clinical and laboratory observationsAn Investigation of Connections between Birth Defects and Cancers Arising in Adolescence and Very Young Adulthood

This study investigated the relationship between birth defects and cancer in adolescents and very young adults using California's population-based registries. Although overall cancer risk was elevated among individuals with chromosomal birth defects, this was not observed in those with nonchromosomal birth defects, as was demonstrated previously in younger children.
