In a study of 70 patients with 75 histologically proven fibroadenomas of the breast, a biphasic peak incidence was recorded, initially in their late 20s to early 30s with a second unexpected peak in their late 40s to early 50s. These lesions averaged 2.8 cm in diameter, two thirds were located in the lateral quadrants of the breast, and 10 percent were multiple. There was a significantly higher incidence among nonwhite than white women when compared to census figures and hospital admission data. The corrected recurrence rate was 17 percent. An inordinately high number of patients under 40 years of age in this series were nonwhite. Family history demonstrates a significantly high incidence of breast disease of all types in first-degree relatives.
在一项针对70例患者的研究中，这些患者共有75个经组织学证实的乳腺纤维腺瘤，记录到了双相高峰发病率，最初在20多岁晚期至30岁早期，第二个意外高峰出现在40多岁晚期至50岁早期。这些病变平均直径为2.8厘米，三分之二位于乳腺的外象限，10%为多发。与人口普查数据和医院入院数据相比，非白人女性的发病率明显高于白人女性。校正后的复发率为17%。该系列中40岁以下的患者中，非白人的数量异常之高。家族史显示，一级亲属中各类乳腺疾病的发病率显著较高。
