Breast cancer (BC) is a serious threat to women's health. Higher BC risk is allegedly related to personal lifestyle like diet. However, it is still unclear how dietary quality affect BC survivors. This meta-analyse aimed to figure out it. The highest and lowest categories of healthy and unhealthy dietary patterns were compared by using the random-effects meta-analyses, which combined relative risks (RRs) and 95% confidence intervals (CIs) that were multivariable-adjusted. 11 eligible articles, including two RCTs, three case-control studies, and six cohort studies, were found and included in this paper after they met the inclusion criteria. According to the pooled analyses, when compared to the lowest group, women with the highest quality healthy diet (highest quintile/quartile/tertile) had 24% lower risk of overall death(random effects (RR = 0.76; 95%CI = 0.67-0.86), 16% lower risk of BC specific death (random effects (RR = 0.84; 95%CI = 0.75-0.94), 28% lower risk of No-BC death (random effects (RR = 0.72; 95%CI = 0.63-0.83),and 4% higher risk of recurrence (random effects (RR = 1.04; 95%CI = 0.97-1.12). According to our meta-analysis, consuming a high-quality healthy diet was linked to a lower risk of all-cause death. The results could have significant effects on encouraging the use of daily dietary treatment regimen to benefit breast cancer patients. To achieve better long-term survival and better quality of life for BC patients, definitively establishing effective interventions will necessarily require further researches.
