I was also pregnant when diagnosed. I have talked to a lot of pregnant women and there are also several on the YSC web site. Less than half are her2 positive. I agree with the previous poster that it seems like more than pregnant women's fair share are her2+, but it's because it's so much more common in young women. I read somewhere once that in women under 40 who are diagnosed with breast cancer, 25% are either pregnant or within a few years of having a baby. Well, if you think about it.....with women under 40, likely 25% of them in general are either pregnant or a few years post partum at any given time, so that's not really out of line. If 40% of women under 40 are her2 positive, then it would seem like there are many more her2+ pregnant women than the rest of the population.
