Does My Exposure to Radiation and/or Chemotherapy Increase the Risk of Congenital Abnormalities in My Children Conceived in the Future?
Most studies addressing this issue have failed to show an increased incidence of congenital malformations when the mother or father was previously treated for cancer. The conclusions are somewhat limited by the relatively small number of babies born to cancer survivors (although this number is increasing annually) and by the fact that most analyses are based on data for survivors of Hodgkin’s disease (a type of lymphoma).
There is some evidence to suggest that women previously treated with chemotherapy and/or radiation who are now fertile have a higher incidence of miscarriage.
Cancer survivors of both sexes who are contemplating pregnancy should strongly consider getting genetic counseling. In this cutting-edge field of medicine, experts in genetic counseling are best equipped to help you make an informed decision with the information available.
(for men) When Can I Think about Safely Fathering a Child?
Discuss with your oncologist your desires, needs, and concerns regarding conception. In general, you will need to wait until the quality and counts of your sperm appear satisfactory. Wait until you feel ready for the stress of a new baby emotionally, physically, and financially. Recovery from cancer entails a stressful transition, and you should take on additional major stresses only after weighing the pros and cons, and the risks and benefits to everyone involved.
(for women) When Can I Think about Becoming Pregnant?
•when you are felt to be adequately recovered to carry a full-term pregnancy
•when your cancer situation is felt not to be jeopardized by the normal changes of pregnancy, such as the hormonal changes
•when your cancer situation will no longer require tests that would put a fetus at risk, such as X rays or scans
When possible, wait until you feel ready to handle the physical, emotional, and financial stress of a new baby.
What Are My Options for Becoming Pregnant If My Cancer Treatment Has Permanently Decreased My Fertility (Made Me Subfertile) or Made Me Permanently Sterile?
Various options are available for women rendered subfertile or sterile by their cancer treatment. For example, some women are candidates for ovum donation (implantation of an egg from a donor). If childbearing is an issue, seek consultation with specialists in assisted reproductive techniques. The names of fertility clinics or services that specialize in this area can be obtained from your primary care giver or the gynaecology department of your local hospital. You should review with your oncologist any decisions regarding treatment for fertility before you proceed. The potential for problems or risks in your specific case as a result of proposed treatments must be considered.
