I am a 40 year old man who has been successfully treated for nasopharyngeal cancer in 2002-03 with induction chemotherapy followed by IMRT radiation (I was 37 then). Things have been going well.

I had understood that it was inadvisable for me to have children for some time after I completed treatment because the chemotherapy or radiation or some combination had a small risk of teratogenic side effects after treatment. I am unsure to what degree (if any) that these risks remain in light of the fact that I completed treatment 2 and a half years ago.

Well, you can probably guess where this is heading. My wife (who is 42) is pregnant (8 weeks). Does anyone know if there is anything special that we should do, any test that we should run, or any risk that we should educate ourselves about?
