Chemotherapy does not affect the development of the fetus.
Cancer in pregnant women can be treated without having to carry the pregnancy to term, and it has little impact on children.
According to the conclusions of several studies published in The Lancet Oncology journal, pregnancy should be preserved whenever possible in breast and gynecological cancers. In the case of hematological cancers, there may be problems during the first trimester.
The results of these studies show that children exposed to chemotherapy in utero show no growth retardation or increased central nervous system or heart related problems compared to the general population.
In general, the children showed normal growth and development. Although in one of the studies, prematurity was the risk that was identified among children exposed to chemotherapy during pregnancy, these children, although they had lower measures of cognitive development, these were similar to those observed in other studies with premature babies without exposure to chemotherapy.
Furthermore, the results also
show that these mothers do not face an increased risk of mortality
cancer than other non-pregnant cancer patients.
