A study in the Netherlands, which looked at the long-term risk of cancer for children who were not physically captured, concluded that IVF children do not appear to be at greater risk of developing cancer.
Until now, there was conflicting evidence as to whether assisted reproduction is associated with an increased risk of cancer. For the first time a study followed a large number of children (47,690 of whom 24,269 were born with assisted reproduction and 231 had cancer) for a long time (21 years on average). The research concluded that the risk of cancer is broadly the same as that of the general population.
The researchers, headed by Professor Florea van Liuen, head of the Department of Epidemiology at the Amsterdam Cancer Institute in Amsterdam, published the publication in Human Reproduction magazine of the European Society of Human Reproduction and Embryology, analyzed data from 12 Dutch fertility clinics .
The risk of cancer has been found to be slightly elevated – albeit not statistically significant – to children born by the microsomal or intracerebral infusion method (ICSI) and to those derived from embryos that were frozen before use in fertility treatment.
There was a very small but not statistically significant increase in the risk of lymphoblastic leukemia and melanoma, according to researcher Maddy Span, these findings may be due to fate, so they have to be interpreted with caution, says RES-EIA.
“The findings provide reassuring indications that children captured after fertility treatments do not have an increased risk of cancer after an average follow-up of 21 years. However, as more and more children are born through microfouling and cryopreservation of the embryos, the long-term cancer risk should be explored in larger numbers of children, “said van Liuwen.
