Basal cell carcinoma

In 1984, the incidence of non-melanoma skin cancer was estimated to be 1372 for men and 702 for women per 100,000 population, the highest recorded incidence rates in the world. Rates in men were nearly double the rates in women and age-specific incidence rates increased curvilinearly with age. There were, on average, 1.4 skin cancers per person with non-melanoma skin cancer and the ratio of basal cell carcinomas to squamous cell carcinomas was approximately three to one.
