ABSTRACT
Skin cancer is the most prevalent malignancy in fair skinned people (Diepgen
and Mahler, 2002; Ley, 2002). The incidence of both the more common non-
melanoma skin cancer (NMSC) and the more lethal cutaneous melanomas
continue to increase, reaching epidemic numbers. NMSC accounts for up to
one third of all cancers in the United States and in Australia. According to recent
population based studies from Australia, the incidence rate is over 2 percent for
basal cell carcinomas in males and 1 percent for squamous cell carcinomas.
