While pregnancies enabled by in vitro fertilisation (IVF) have faced more difficulties, with children born earlier and smaller, according to a new study, they may also raise risk of cancer in babies.
IVF is associated with birth defects and imprinting disorders. Because these conditions are associated with an increased risk of childhood cancer, many of which originate in utero, descriptions of cancers among children conceived via IVF are imperative, said researchers from the University of Minnesota in the US.
The study, published in JAMA Pediatrics journal, found that the overall cancer rate among IVF children was about 17 per cent higher than non-IVF children.
In addition, the rate of liver tumours was over 2.5 times higher among IVF children than naturally conceived children.
However, there was no difference in the rates of other cancers between the two groups.
