Known clinical, lifestyle and socioeconomic risk factors were evaluated and adjusted for in multivariate analysis. We found a modest but significant association between pre‐diagnostic alcohol consumption and breast cancer recurrence with a median follow‐up of six years after date of diagnosis, both when using baseline measures of alcohol intake (HR, 1.65; 95% CI, 1.02–2.67; >2 units/day vs . ≤1 unit/day) and cumulated alcohol intake (HR, 2.02; 95% CI, 1.06–3.85; >40 drinking years vs . 0
