Records of the Swedish Twin Register for those born (n = 83,) were linked to the Swedish Cancer Register () and the Swedish Cause-of-Death Register (). To explore the possibility that both prenatal x-ray examination and childhood cancer might be attributable to a separate, common risk factor, and since radiographic examination of women who are pregnant with twins has usually been performed because of the twin pregnancy rather than because of other diagnostic concerns, the incidence of cancer.
