Background: Breast cancer is the most frequently diagnosed malignancy and the leading cause of cancer death among women worldwide. In Morocco, there have been few recent descriptive studies on female breast cancer. The aim of this study was to describe the latest available incidence and mortality rates of breast cancer among Moroccan women and to compare them with rates in other regional and Western countries. Methods: For this descriptive study, Moroccan incidence data were obtained from the most recent reports of the cancer registries of Casablanca and Rabat. Information on breast cancer incidence for different countries were obtained primarily from publicly available cancer registries and Cancer Incidence in Five Continents, Volume X. Mortality data were extracted from the GLOBOCAN 2012 published by the International Agency for Research on Cancer. Results: The age-standardized incidence (World) rate of breast cancer in Moroccan women increased from 35.0 to 39.0 per 100,000 women between 2004 and 2008, showing an annual increase of 2.85 %. The highest incidence rates were registered in the age groups of 45-49, 50-54 and 55-59 years (106.1, 108.2 and 108.5 respectively). Sixty-nine percent of female breast cancer cases were diagnosed at stages II and III. In 2012, the estimated number of women who died of breast cancer in Morocco was 2,878. The crude, age-standardized (World) mortality rates were 17.3 and 18.0 per 100,000, respectively. Conclusion: Although the incidence of female breast cancer in Morocco is lower than in Western countries, evidence shows that the rate is rising. This increase of breast cancer incidence has been observed in parallel with changes in reproductive behavior and adoption of a Western lifestyle. Prevention policies need to be implemented.

<P>Epigenetic regulation of imprinted genes is regarded as a highly plausible explanation for linking dietary exposures in early life with the onset of diseases during childhood and adulthood. We sought to test whether prenatal dietary supplementation with docosahexaenoic acid (DHA) during pregnancy may modulate epigenetic states at birth. This study was based on a randomized intervention trial conducted in Mexican pregnant women supplemented daily with 400 mg of DHA or a placebo from gestation <I>week 18–22</I> to parturition. We applied quantitative profiling of DNA methylation states at <I>IGF2</I> promoter 3 (<I>IGF2</I> P3), <I>IGF2</I> differentially methylated region (DMR), and <I>H19</I> DMR in cord blood mononuclear cells of the DHA-supplemented group (<I>n</I> = 131) and the control group (<I>n</I> = 130). In stratified analyses, DNA methylation levels in <I>IGF2</I> P3 were significantly higher in the DHA group than the control group in preterm infants (<I>P</I> = 0.04). We also observed a positive association between DNA methylation levels and maternal body mass index; <I>IGF2</I> DMR methylation was higher in the DHA group than the control group in infants of overweight mothers (<I>P</I> = 0.03). In addition, at <I>H19</I> DMR, methylation levels were significantly lower in the DHA group than the control group in infants of normal weight mothers (<I>P</I> = 0.01). Finally, methylation levels at <I>IGF2/H19</I> imprinted regions were associated with maternal BMI. These findings suggest that epigenetic mechanisms may be modulated by DHA, with potential impacts on child growth and development.</P>
