The role of spontaneous and induced abortion on breast cancer risk is examined among 267,361 women recruited into the European Prospective Investigation into Cancer and nutrition between 1992 and 2000. The data were collected from 20 centers, across 9 countries, and included information on a total of 4,805 women with breast cancer, of whom 1,657 reported having ever had any type of abortion. Overall, the relative risk of breast cancer in women who reported ever having had a spontaneous abortion was not significantly elevated when compared with women who reported never having had such an abortion (RR = 1.07, 95% CI = 0.99-1.14). However, there was some evidence of a slight increase in the risk of breast cancer among women who reported having had 2 or more spontaneous abortions (1.20, 1.07-1.35). The relative risk of breast cancer among women who reported ever having had an induced abortion when compared to women who reported never having had an induced abortion was 0.95 (0.87-1.03). Overall, the findings provide further unbiased evidence of the lack of an adverse effect of induced abortion on breast cancer risk.
Birth and abortion rates in Sweden have fluctuated since 1980 while the proportion between the rates are the same at the beginning and end of the period. An increase in birth rates in the late 1980s resulted in a peak in 1991 and 1992, with 124,000 live births each year. Thereafter followed a steady decline in the rate until 2000, when the number of live births was about 90,000. At that point, the trend changed to an increase. The aim of this analysis was to investigate any relation between employment rates and the number of live births among women aged 20-34, and at the same time to explore the trend for abortion rates compared to the trend for live births. The relation between employment status and live birth rate is statistically more significant for women than men, and the rates have a higher correlation for the period after 1986. Young adults in this age group are vulnerable to economic cycles that can explain this covariation but the decline in birth rates in economically developed societies has multidimensional aspects and many other possible explanations. Much has been done in recent years in Sweden to decrease household inequality for families with children to avoid the risk of relative poverty, but the fact that there is no explicit health policy to reduce the abortion level that remain unchanged since the early 1980s may appear as a notable lack of strategy in a country with many other health-related goals.
BACKGROUND: Nitric oxide (NO) is a factor in cervical ripening, perhaps under the control of progesterone. We studied the effects of the antiprogesterone mifepristone on the release of NO and on the expression of inducible NO synthase (iNOS) and endothelial NO synthase (eNOS) in the uterine cervix of women in early pregnancy. METHODS: Thirteen women were treated with oral mifepristone (200 mg), and 15 women were studied as controls. Cervical fluid samples were collected before treatment then hourly up to 3 h, and the samples were assayed for the concentration of nitric oxide metabolites (NOx). In addition, cervical biopsy samples from six women treated with mifepristone and from six controls were assessed for iNOS and eNOS by immunohistochemistry and Western blotting. RESULTS: In 1-3 h, mifepristone induced 7.4- to 17.2-fold elevations in cervical fluid NOx concentrations; no change was seen in the controls. The expression of both iNOS and eNOS was detected in the cervical cells. The expression of cervical iNOS was strong in five of the six women treated with mifepristone but was not strong in any of the six control women. CONCLUSION: This is the first study to show that mifepristone stimulates the release of NO and the expression of iNOS in cervical cells of women in early pregnancy. This may be one mechanism by which mifepristone initiates cervical ripening.
