We compiled these studies to confirm the reality of the significant association reported in the first, 1996 review of induced abortion as a risk factor, independent of abortion's known effect in abrogating the protection afforded by full-term pregnancy.
METHODS
We searched the medical literature for English language studies on breast cancer incidence in…
