Incidence rates of selected cancer sites reported by the California Tumor Registry and the New Mexico Tumor Registry are analyzed to study ethnic differences in cancer in the United States. The white majority population shows high incidence of lung and breast cancers. Black males show the highest prostatic cancer rate. Data also confirm the unusually high incidence of nasopharyngeal cancer and low prostatic cancer rates among Chinese males. The Japanese have the highest stomach cancer incidence among all the ethnic groups analyzed. A comparison with the cancer incidence in the same ethnic groups in their native countries reveals the impact of environmental or cultural changes on lung, breast, and stomach cancers, and a possible genetic influence on the high incidence of nasopharyngeal cancer among the Chinese population in the United States.
对加利福尼亚肿瘤登记处和新墨西哥肿瘤登记处报告的特定癌症部位的发病率进行分析，以研究美国癌症方面的种族差异。白人多数群体显示出肺癌和乳腺癌的高发病率。黑人男性前列腺癌发病率最高。数据还证实了中国男性中鼻咽癌的异常高发病率和低前列腺癌发病率。在所分析的所有种族群体中，日本人胃癌发病率最高。将这些种族群体在美国的癌症发病率与其在本国的发病率进行比较，揭示了环境或文化变化对肺癌、乳腺癌和胃癌的影响，以及对美国华裔人群中鼻咽癌高发病率可能存在的遗传影响。
