Skin Cancer are the more frequent malignant tumors in the caucasian population, however significant and particular difference are present in World Cancer Registries incidence data. The analysis of the temporal trend, more than the geographical trend, is thicken by three characteristics: incidence, relation between diagnosis and treatment, register rate. The British Columbia Cancer Registry probably gives the more reliable valuation and shows an incidence doubled for these tumors during the period of five years considered, (1973-1987). These trends are equal in male and female and also in the two type of tumors for all sites. The analysis of the Cancer Registries includes Italy as a country with an intermediate risk, the relation between male and female and the correlation with the age are similar among the Cancer Registries as seen in the caucasian population. The analysis of the cut off rate (35-64 years) and cumulative risk (0-64 years, 0-74 years) shows the importance of the age of insorgence.
皮肤癌是白种人人群中较为常见的恶性肿瘤，然而世界癌症登记处的发病率数据存在显著且特殊的差异。对时间趋势的分析，而非地理趋势，因三个特征而变得复杂：发病率、诊断与治疗之间的关系、登记率。不列颠哥伦比亚癌症登记处可能给出了更可靠的评估，并显示在所考虑的五年期间（1973 - 1987年）这些肿瘤的发病率翻了一番。这些趋势在男性和女性中以及所有部位的两种肿瘤类型中都是相同的。癌症登记处的分析将意大利列为中等风险国家，男性和女性之间的关系以及与年龄的相关性在癌症登记处中与白种人人群中所见相似。对截止率（35 - 64岁）和累积风险（0 - 64岁，0 - 74岁）的分析显示了发病年龄的重要性。
