Mediterranean diet may improve prognosis in BC

Key clinical point: Adherence to a Mediterranean diet before being diagnosed with breast cancer (BC) may improve survival outcomes, particularly in postmenopausal women.

Major finding: A low vs medium adherence to Mediterranean diet was associated with a 13% higher risk for all-cause mortality (hazard ratio [HR] 1.13;  95% CI 1.01-1.26). The risk for overall mortality reduced by 8% (HR 0.92;  95% CI 0.87-0.97) for every 3-unit increase in the adapted relative Mediterranean diet score, with the association sustaining in case of postmenopausal women only.

Study details: Findings are from an analysis including 13,270 women with incident BC from a prospective, multicenter European cohort of 318,686 women.
