A review of 1059 patients seen in office consultation from 1970 to 1975 for breast disorders revealed that patients with clinically benign disorders were six times as numerous as those with breast cancer. Only 11% of patients with breast cancer had had a previous benign breast-biopsy specimen and on average they were 20 years older than the peak age for benign clinical disease. Of the 163 patients with a previous benign breast-biopsy specimen only 14 (9%) had breast cancer compared with 13% in women without such a history. It is concluded that clinical benign breast disorders do not predispose patients to cancer, and such women should not be singled out for special study.
一项对1970年至1975年间因乳腺疾病前来门诊咨询的1059例患者的回顾显示，临床诊断为良性疾病的患者数量是乳腺癌患者的6倍。仅有11%的乳腺癌患者曾有过良性乳腺活检标本，而且平均而言，她们比良性临床疾病的高发年龄大20岁。在163例曾有过良性乳腺活检标本的患者中，只有14例（9%）患有乳腺癌，而无此类病史的女性中这一比例为13%。研究得出结论，临床诊断的良性乳腺疾病不会使患者易患癌症，不应将这类女性挑选出来进行专门研究。
