Alcohol and breast cancer: an overview

We have reviewed available reports from 1974-1987 linking alcohol consumption with breast cancer. Although three prospective studies show a slightly increased risk of breast cancer for consumers versus non-consumers of alcohol, the results of correlation studies and case control studies have been inconsistent. In both positive and negative studies the amount of alcohol consumed by women with breast cancer was low, and if there is an association between alcohol and breast cancer, then it would appear that complete abstinence would be required to reduce the risk of this disease. At present, it seems premature to consider such a drastic recommendation until further information becomes available.
