Dermatologists have repeatedly criticized that the public health importance of nonmelanoma skin cancers is not appropriately reflected by the patient-based cancer incidence rates of population-based cancer registries. The aims of this study were to estimate the patient incidence rates of squamous cell carcinoma (SCC), basal cell carcinoma (BCC), and skin melanoma, and to study the effect of multiple primary skin tumors on the incidence rates. ⋯ Patient incidence rates of BCC and SCC substantially underestimate the burden of nonmelanoma skin cancer in the population.
