title: Skin cancer screening on a fishing island and in an inland agricultural area of Japan.
abstract: We performed skin cancer screening from 2000 to 2004 at two locations in Japan's Oita Prefecture: Himeshima, a small fishing island, and Naoiri, an inland agricultural area. We found 108 and 21 cases of AK in Himeshima and Naoiri, respectively. None of the AKs transformed into SCC, and 21.7% of the AKs underwent spontaneous remission during our observation period. The prevalence and incidence of AK in Himeshima were five times higher than in Naoiri: 1,399 and 826 per 100,000 population, respectively, in the fishing village, vs. 261 and 164 in the agricultural community. Seven and three cases of BCC were observed in Himeshima and Naoiri, respectively. There were two cases of SCC in Himeshima. The highest risk ratio of skin types I to III was 9.2 in Himeshima. Although people engaged in outdoor occupations are thought to be more prone to skin cancer and precancerous skin lesions, our results suggested different potentials for AK in people engaged in different outdoor occupations.
