Cumulative risk of cancer incidence of melanoma of skin (ICD-10: C43) and other cancer of skin (ICD-10: C44) to age 69 was calculated with data from Cancer Incidence in Five Continents Vol. VIII (1). Cumulative risk is defined as the probability that an individual will develop the disease in question during a certain age span, in the absence of other competing causes of death.

The comparisons of the cumulative risk of incidence of skin melanoma among 22 registries (and ethnic groups) are shown in Fig. 1. SEER (Surveillance Epidemiology and End Results) white in USA and European registries showed higher cancer risk than East Asia in both sexes. The cancer risk in SEER white in USA is far higher than in SEER black and East Asian immigrants in USA. Though several East Asian immigrant populations in USA showed higher cancer risk than those lived in their homeland (Japanese male and Korean female in Los Angeles, USA, and Japanese female in Hawaii), this tendency was not consistent in other populations.
