ABSTRACT
Cancer of the skin is a very common form of neoplasm. These cancers are com-
monly divided between cutaneous melanoma and nonmelanoma skin cancer.
Cutaneous melanoma has shown a rapid increase of incidence in last decades,
and because of its poor prognosis, this neoplasm has received a great deal of
interests in epidemiological studies. In marked contrasts, and despite the import-
ant prevalence of this disease in the population, few reliable epidemiological data
exists about nonmelanoma skin cancers.
