Melanoma
Incidence, Mortality, and Trends of Nonmelanoma Skin Cancer in Germany
Increasing incidence rates (IRs) of nonmelanoma skin cancer (NMSC) in white populations have been described worldwide. Cancer registry data from the Saarland and Schleswig-Holstein federal states were used to analyze incidence and mortality trends in Germany. Age-standardized rates were compared with crude rates to assess disease burden. Joinpoint regression models were used to estimate annual percentage changes and 95% confidence intervals, allowing us to assess temporal trends between 1970 and 2012.Cigarette Smoking and the Risks of Basal Cell Carcinoma and Squamous Cell Carcinoma
Sunlight is the principal environmental risk factor for keratinocyte cancers, but other carcinogens have also been implicated, including tobacco smoke. Findings have been conflicting, however. We investigated associations between cigarette smoking and incidence of basal cell carcinoma (BCC) or squamous cell carcinoma (SCC) in QSkin, a prospective study of skin cancer (N = 43,794). Smoking history was self-reported at baseline; newly diagnosed BCCs and SCCs were ascertained through data linkage and verified by histopathology reports.
