Epidemiology of basal cell carcinoma in the United Kingdom: incidence, lifestyle factors, and comorbidities.

Background:Little is known about the epidemiology of basal cell carcinoma (BCC).Methods:Using the Clinical Practice Research Datalink, we calculated annual incidence rates. In a case-control analysis, we examined lifestyle factors and comorbidities.Results:Incidence rose significantly between 2000 and 2011. Basal cell carcinoma risk was increased in alcohol drinkers (slightly) and immunocompromised patients, but reduced in smokers and individuals with abnormal weight.Conclusions:Basal cell carcinoma places a growing public health burden. Lifestyle factors do not play a major role in pathogenesis, but immunosuppression is important. [ABSTRACT FROM AUTHOR]
