Miscarriages do not increase breast cancer risk, since they are associated with low oestrogen levels that do not cause breast growth

Junk science alert!

First, most miscarriages are caused by a genetic defect in the fetus, not by low estrogen levels in the mother.

I can't tell why you have a problem whith the statment you italicized.

Because 1) low estrogen is NOT the cause of most miscarriages, 2) in the cases where it is, the women in question would have a lower than normal risk for breast cancer to begin with, and 3) in the majority of miscarriages, which are NOT caused by low estrogen, the author's claim of a scientific explanation for a different effect on breast cancer risk depending on whether a first trimester pregnancy is terminated naturally or artificially, goes out the window -- because it was based on hte non-factual allegation that low estrogen is the cause for the difference.

BTW, last year abortion-breast-cancer-link promoter Saundra Duffy posted a transcript of an interview with the leading "researcher" who touts this link, Dr. Joel Brind, in which he said his research showed that miscarriage caused the same elevated breast cancer risk as induced abortions. I think he's changed his tune since then, as he realized it wasn't popular with the let's-fight-abortion-by-scaring-women-about-breast-cancer crowd, which is basically his only audience.
