The purpose of this study was to assess the relationship between daily coffee consumption and nonmelanoma skin cancer. This study was a cross-sectional analysis of women enrolled in the Women's Health Initiative Observational Study (n=93 676). As nearly all cases of self-reported nonmelanoma skin cancer occurred among Caucasian women (97.8%), we focused our analyses on this group. Compared with nondrinkers, women drinking only caffeinated coffee on a daily basis had a 10.8% lower prevalence of nonmelanoma skin cancer. Consumption of six or more cups of caffeinated coffee per day was associated with a 36% reduction in nonmelanoma skin cancer. After adjusting for various demographic and life style variables, daily consumption of six or more cups was associated with a 30% reduced prevalence of nonmelanoma skin cancer. In contrast to caffeinated coffee, daily consumption of decaffeinated coffee was not associated with a significant change in self-reported nonmelanoma skin cancer for Caucasian women. Daily caffeinated coffee consumption was associated with a dose-related decreased prevalence of nonmelanoma skin cancer in Caucasian women.
