Children born after use of assisted reproduction technology do not have an increased risk for any cancer, but those born after frozen-thawed embryo transfer have an increased risk for childhood cancer, according to a study published online 1 September in PLOS Medicine.

Nona Sargisian, from Sahlgrenska University Hospital in Gothenburg, Sweden, and colleagues conducted a registry-based cohort study using data from Denmark, Finland, Norway and Sweden involving 7,944,248 children, of whom 2.2% were born after use of assisted reproduction technology (ART).
