title: UVA, UVB and incidence of cutaneous malignant melanoma in Norway and Sweden.
abstract: Latitudinal dependencies of UVA and UVB were studied together with relevant epidemiological data for squamous cell carcinoma (SCC) and cutaneous malignant melanoma (CMM) in Norway and Sweden. Our data support the hypothesis that solar UVA radiation may play a role for CMM induction. The etiologies of SCC and CMM are different according to a latitudinal dependency and differences in age curves. Sun exposure patterns, age-related decay rates of repair of UV damage and sex hormones may play different roles for the two skin cancers. Also, UVB induction of vitamin D may be involved. CMM incidence rates among young people have decreased or been constant since about 1990 in Norway and Sweden. All reasons for UVA contributing to CMM will be discussed.
