Methods: We performed an electronic search using PubMed, Cochrane, Scopus Google Scholar, Persian database (Iran Medex, magiran) to identify relevant studies. We summarized the findings of 8 papers in this review. Results: Although, three cohort studies were not overall identified a protective effect of Conjugated linoleic acid on breast cancer, one of them showed an inverse association after adjusting for age. Also, this impact was seen when the Conjugated linoleic acid intake of population were examined as usual daily food consumption. Also, among case-control studies, a weak inverse association among post-menopausal women was reported.

Conclusions: Lacking published evidence suggested inconsistent results. So, further well designed studies are .
