: The association between pre-diagnostic alcohol consumption and breast cancer recurrence and breast cancer specific mortality was investigated in 1,052 women diagnosed with early breast cancer in a prospective cohort of 29,875 women. 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
