To the Editor: The combined analysis of 6 cohort studies by Dr Smith-Warner and colleagues1 provides evidence that alcohol consumption is associated with increased risk of breast cancer. Within a range between minimal and moderate consumption, the study demonstrates a dose-response relationship between alcohol intake and breast cancer risk. The intriguing finding is that women who consume a relatively large amount of alcohol do not show further increase in the risk of breast cancer. If this observation is true, it may indicate a potentially important biological mechanism underlying the association of alcohol with breast cancer risk.
