According to a new study, female childhood cancer survivors face a lower likelihood of becoming pregnant than women in the general population, but once pregnant, they are not more likely to undergo an abortion.
The findings were published online in the journal 'CANCER'. Cancer survivors might be reluctant to start a family due to concerns for their children's health as well as the potential recurrence of their own cancer. This could lead to a greater likelihood of induced abortions in female survivors who become pregnant.
To examine whether pregnancies of childhood cancer survivors are more likely to end with induced abortions, Johanna M Melin, MD, PhD, of the Finnish Cancer Registry in Helsinki, Finland, and her colleagues examined data from Finnish registers on cancer, births, and induced abortions.
When the researchers compared 420 first pregnancies of childhood cancer survivors with 2,508 first pregnancies from the general population in 1987 to 2013, survivors had a 28 percent lower probability of becoming pregnant compared with women in the general population, but their risk of a first pregnancy resulting in an induced abortion was similar.
"Our study shows that the risk of terminating a pregnancy is similar in childhood cancer survivors and population controls, suggesting that female childhood cancer survivors are as willing as their peers to continue the pregnancy and become parents," said Dr Melin.
"Also, research has found no increased risk for congenital anomalies in children born to cancer survivors. In our study, termination of pregnancy due to a congenital anomaly or birth defect of the fetus was very rare in childhood cancer survivors," added Melin.
Melin noted that the reduced probability of pregnancy in childhood cancer survivors seen in this study highlights the persisting need for interventions to preserve patients' fertility during treatment. This supports the American Cancer Society's Preserving Fertility in Female Cancer Patient initiative.
