Alcohol and breast cancer

A letter to the editor critiques a recent editorial reporting an association between breast cancer and alcohol consumption, and summarizes 10-year breast cancer prevalence data that indicates the absence of such an association. A response is provided by the author of the editorial, critiquing the subject letter and associated data, and arguing strongly on the validity of the alcohol-breast cancer association. Seven additional letters to the editor on this topic are included, generally supporting the epidemiological finding of increased breast cancer risk with alcohol consumption.(wz)
