abstract: OBJECTIVE
  The association between fish consumption and the risk of breast cancer has not been established yet. Results from epidemiological studies are inconsistent. We conducted a meta-analysis to examine the association between fish consumption and the risk of breast cancer.
  
  
  METHODS
  We identified eligible studies in Medline and EMBASE up to February 2015 and the reference lists of original studies and review articles on this topic. Summary relative risks with their 95% confidence intervals were calculated with a random-effects model.
  
  
  RESULTS
  We identified 27 studies eligible for analysis. The summary relative risk of breast cancer for the highest consumption of fish compared with the lowest was 0.96 (95% CI = 0.87-1.07), with evidence of heterogeneity (Q = 69.09, p < 0.001, I2 = 68.0%). Four studies investigated lean fish consumption and revealed that there was a small increase in the risk of breast cancer (summary RR = 1.09, 95% CI = 1.00-1.19). As only four studies were included in the subgroup analysis, results must be interpreted with caution.
  
  
  CONCLUSIONS
  The overall current literature on fish consumption and the risk of breast cancer suggested no association. Further well-designed prospective studies are needed to explore fish consumption in relation to breast cancer risk.
