Epidemiology of basal cell carcinoma: scholarly review

Basal cell carcinoma (BCC) is the most common cancer in white-skinned individuals with increasing incidence rates worldwide. Patients with BCC place a large burden on healthcare systems, because of the high incidence and the increased risk of synchronous and metachronous BCCs and other ultraviolet radiation (UVR) related skin cancers (i.e. field cancerization). As a result, the disability-adjusted life years and healthcare costs have risen significantly in recent decades. BCC is a complex disease, in which the interplay between UVR, phenotype (UVR-sensitive) and genotype (somatic mutations and germline mutations/polymorphisms) fulfils a key role in the aetiopathogenesis. Prevention programmes with continual refinements and improvements could be of major importance in tackling the growing skin cancer problem. To provide the most appropriate BCC care, physicians should engage in shared decision-making and choose their treatments wisely.
