Sam,

My doctors didn't say anything explicitly about possible genetic risks in pregnancy - but I don't think I really pushed them on that point either. At that time I was so stunned by the diagnosis and what was involved in treatment that I pretty much concluded on my own that I couldn't take on any attempts at pregnancy for quite awhile.

Are you being treated at a comprehensive cancer center? If you are, I suspect there is a fairly good level of experience there in dealing with pregnancy issues post-radiation. Since your radiation is going to be in the head/neck region, I'm not sure I know why there could be a genetic risk, but then I'm not a doctor. My biggest concern would be along the lines of what Minnie said -- getting proper nutrition during radiation (AND its aftermath) is an extreme challenge by itself, without adding on the nutritional needs connected with a pregnancy.
