Cancer Mortality After Nonmelanoma Skin Cancer—Reply

Abstract
In Reply: We thank Dr Spratt for his interest in the association we observed, although in our study the age-adjusted death rate due to cancers of the colon and rectum was not higher among either men or women who reported a history of nonmelanoma skin cancer. However, a previous study based on a cancer registry found that the incidence of colon cancer was positively associated with a skin cancer history among men (standardized incidence ratio [SIR], 1.2; 95% confidence interval [CI], 1.06-1.42), but not women (SIR, 0.85; 95% CI, 0.71-1.01).1
