A study that was carried out on menopausal women showed that fish oil might protect women from the dangers of breast cancer.

Extensive researches were performed on omega-3 fatty acids like DHA and EPA to test their influence on improving the healing effect of chemotherapy used in breast cancer treatment. The researches revealed promising results that these kinds of fish oil actually might help in fighting breast cancer and in preventing the cancerous cells from infecting other tissues or organs.

The study depended on comparing two n-3 PUFAs, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) on CXCR4 expression and activity in the MDA-MB-
231 breast cancer cells with an acid high in stearin, a saturated fatty acid, for any anticancer effect.

This study proved Omega-3 fatty acids to reduce the "migration" of cancer cells to other tissues, however, the study also proved that Omega-3 acids do not have any direct effect on lessening the number of cancer cells.

Women, who were taking fish oil at the start of the study, were less likely to develop ductal carcinoma of the breast, which is the most common type of breast cancer.

According to the statistics presented by the National Cancer Institute, about 175,000 women are diagnosed with breast cancer every year in the United States, and 45,000 of them are killed by the disease.
