The proposal put forward by Boniol et al. to further investigate the role of solaria in the development of cutaneous melanoma is interesting from an etiologic as well as a public health perspective. They hypothesize that solarium users will be more likely than nonusers to develop melanomas at habitually covered sites (such as the trunk) and will have higher nevus counts overall.

The correspondence by Boniol et al. highlights the nature and intermittency of UV exposure as a driving force underlying the development of melanoma at anatomic sites. By contrast, we have approached this important issue from the perspective of personal susceptibility (1). Although the importance of UV exposure in the development of melanoma is well documented (2,3), the majority of Australians never develop melanoma despite considerable (and, in many cases, extraordinary) exposure to intense UV radiation, which underscores the importance of individual susceptibility. Clearly, these two views are not mutually exclusive and may ultimately be reconciled as our understanding of melanoma development unfolds.
