The association between nutrition and cancer in general had been a controversial issue between scientists in the last
three decades, because some argued that there is a relationship and some nutrients can help in preventing cancer
occurrence, although this has not been a consistent finding by other studies. Studies were identified through a
systematic review of literature available on PubMed in between 1st January 2010 to 31st December 2013. We
included all studies that assessed nutrition or diet with occurrence or mortality of breast cancer. Out of 42 articles,
we included 8 articles in our screening and discussion. Among these 8 studies, there were 2 case-controls, 3 cohort
and 3 randomized control trials (RCT) studies. Although most studies reported that nutrition isassociated with
decreased risk, some reported the contrary,whereas others reported no relation. It was demonstrated a conflict
between the included papers in regards of the association between nutrition and breast cancer. These finding needs
to be re-evaluated in future studies.
