Aetiology

Authoring team

The principal aetiological factor in BCC development is exposure to ultraviolet (UV) radiation, particularly UVB wavelengths, although UVA also contributes. (1,3)

Meta-analyses confirm a significantly higher incidence among outdoor workers, with risk increasing at lower latitudes. Among White individuals, Fitzpatrick skin type is a strong predictor, with types I and II carrying the greatest susceptibility. (2)

UVB should be viewed as a hazard to children and adolescents, as about one quarter of lifetime exposure occurs before 18 years of age. (4)

Gorlin syndrome - also called Gorlin-Goltz syndrome - is a rare autosomal dominant familial cancer syndrome characterized by numerous basal cell carcinomas (BCCs), along with skeletal, ophthalmologic, and neurologic abnormalities. Multiple neoplasms arise starting in childhood. (5)
