Crucial new research has failed to discover a link between induced or spontaneous abortions (miscarriages) and the incidence of breast cancer in pre-menopausal women. According to researchers at Brigham and Women’s Hospital, Harvard Medical School, and Harvard School of Public Health, “In this cohort study of young women, we found no association between induced abortion and breast cancer incidence and a suggestion of an inverse association between spontaneous abortion and breast cancer incidence during 10 years of follow-up.†The results of the research were published in the April 23 issue of the Archives of Internal Medicine.
The report examined the health histories of 105,716 women who were part of the Nurses’ Health Study II (NHSII). All of the women were between the ages of 29 and 46 when the study began in 1993, and they were each subject to follow-up examinations at two-year intervals until 2003. A total of 16,118 women, or about 15 percent of the cohort, reported a history of induced abortion, while 21,753 of them (21 percent) had a history of miscarriage. During the course of the decade-long study, there were 1,458 new cases of breast cancer reported among the women.
