Incidence of Malignant Melanoma of the Skin in Norway, 1955-1989: Associations with Solar Ultraviolet Radiation, Income and Holidays Abroad

Melanoma incidence in Norway is closely related to local levels of UVB radiation independently of other factors suggesting that local exposures carry significant risk. Risks would probably increase if ozone depletion led to enhanced UVB flux (estimated as 1.6% rise in incidence for each 1% increase in UVB). By the end of the study period income was no longer a significant factor but holidays abroad had started to have a detectable effect on melanoma incidence.
