Soruyu soran doktor hanıma geçmiş olsun der, ekteki makaleyi okumasını öneririm. Özet olarak şöyle diyor: Radyasyon alan kişinin germ hücrelerinde (Yani çocuk olmasını sağlayan yumurtalarında) mutajenik bir etki meydana gelmez. Sadece bu kişilerin bebekleri düşük doğum ağırlıklı olabiliyor. Yani anomali, bebek ölüm riski ve cinsiyette değişiklik olmuyormuş. Umarım yararlı olmuştur.
Saygılarımla.

Abstract
OBJECTIVE: To compare birth outcomes among female survivors of childhood and adolescent cancer who subsequently bear children, relative to those of women without a history of cancer. DESIGN: Retrospective cohort study. SETTING: Four US regions. PARTICIPANTS: Cancer registries identified girls younger than 20 years who were diagnosed as having cancer from 1973 through 2000. Linked birth records identified the first live births after diagnosis (n = 1898). Comparison subjects were selected from birth records (n = 14 278). Survivors of genital tract carcinomas underwent separate analysis. MAIN EXPOSURE: Cancer diagnosis at younger than 20 years. MAIN OUTCOME MEASURES: Infant low birth weight, preterm delivery, sex ratio, malformations, mortality, and delivery method, and maternal diabetes, anemia, and preeclampsia. RESULTS: Infants born to childhood cancer survivors were more likely to be preterm (relative risk [RR], 1.54; 95% confidence interval [CI], 1.30-1.83) and to weigh less than 2500 g (1.31; 1.10-1.57). For the offspring of genital tract carcinoma survivors, RRs were 1.33 (95% CI, 1.13-1.56) and 1.29 (1.10-1.53), respectively. There were no increased risks of malformations, infant death, or altered sex ratio, suggesting no increased germ cell mutagenicity. In exploratory analysis, bone cancer survivors had an increased risk of diabetes (RR, 4.92; 95% CI, 1.60-15.13), and anemia was more common among brain tumor survivors (3.05; 1.16-7.98) and childhood cancer survivors whose initial treatment was chemotherapy only (2.45; 1.16-5.17). CONCLUSIONS: Infants born to female survivors of childhood and adolescent cancer were not at increased risk of malformations or death. Increased occurrence of preterm delivery and low birth weight suggest that close monitoring is warranted. Increased diabetes and anemia among subgroups have not been reported, suggesting areas for study.
