Correlation coefficients were calculated between incidence rates for the most frequent female cancers in populations throughout the world. Positive correlations were generally weak, and we conclude that most female cancers do not share a dominant etiologic factor which is inherent in cancer incidence rates. However, most cancers do exhibit similar age-incidence patterns. We also conclude that the determinant of shape in cancer age-incidence patterns is common to most female cancers, internationally invariant, and independent of the determinants of cancer incidence rates. Breast cancer exhibits an unusual age-incidence pattern with a peculiar dependence on the frequency of breast cancer occurrence.
计算了全球各人群中最常见女性癌症发病率之间的相关系数。总体而言，正相关性较弱，我们得出结论，大多数女性癌症不存在共同的主导病因，而这种病因是癌症发病率所固有的。然而，大多数癌症确实呈现出相似的年龄发病率模式。我们还得出结论，癌症年龄发病率模式的形状决定因素在大多数女性癌症中是共同的，在国际上是不变的，并且与癌症发病率的决定因素无关。乳腺癌呈现出一种不寻常的年龄发病率模式，对乳腺癌发生频率有特殊的依赖性。
