Alcohol Link to Breast Cancer Confirmed

A second analysis of research data accumulated over the last 20 years has confirmed the link between alcohol and breast cancer in women.

An average of two drinks a day, concluded researchers Matthew Longnecker, M.D., and colleagues from the Harvard School of Public Health, can increase the risk of breast cancer by almost 50%. The fact that the risk of breast cancer increased as the amount of alcohol increased lends further support to their findings.

About 13% of all cases of breast cancer in the United States might be attributable to alcohol consumption.

The study was a so-called "meta-analysis," in which researchers reviewed raw data from 21 studies conducted between 1966 and 1987. After developing standards by which to rate the quality of results from each study, they concluded there was a strong association between alcohol consumption and breast cancer.
