Data from a large, international collaborative study were used to evaluate the association between abortions, whether spontaneous or induced, and breast cancer risk. The data from seven countries included 3,958 breast cancer cases and 11,538 hospital controls with information on abortion history obtained through interviews. Compared with nulliparous women with no abortion (baseline), the odds ratios (OR) and 95 percent confidence intervals (CI) were: for nulliparous women with a history of prior abortion, 0.86 (CI=0.68-1.08); for parous women with no history of abortion, 0.63 (CI=0.57-0.69); for parous women with abortion before first birth, 0.82 (CI=0.69-0.97); and, for parous women with abortion only after first birth, 0.70 (CI=0.63-0.79). When restricting analysis to parous women, those with a history of abortion exhibited an elevated OR suggesting a 29 percent risk increa
