A follow-up showed that women who consumed 5–14 g alcohol daily (about 3–9 drinks per week) had an age-adjusted relative risk of BC at 1.3 [95% confidence interval (CI), 1.1–1.7], whereas consumption of 15 g alcohol or more per day was associated with a relative risk of 1.6 (95% CI, 1.3–2.0), and there was evidence of a highly significant increase in risk with further increase in alcohol consumption ( 57 ).
