The early results of a breast screening service in a large retail company have been analysed. Female employees over 35 years of age were offered mammography, thermography and clinical examination, periodically over 51/2 years. One hundred and two cases of proven cancer were found in 21 186 women (4.8 per thousand). Non palpable cancers accounted for 56.9% of the total and 37.3% of these were less than 1 cm in size. Twenty tumours were microscopic. Only 13.7% of cases were known to be node positive and 43% of the cancers occurred in women of less than 50 years of age. The results throughout the whole age range encouraged the original hope that screening and early diagnosis will influence the prognosis of female breast cancer.
一家大型零售公司乳腺筛查服务的早期结果已得到分析。35岁以上的女性员工在5年半的时间里定期接受乳房X光检查、热成像检查和临床检查。在21186名女性中发现了102例确诊癌症病例（每千人中有4.8例）。不可触及的癌症占总数的56.9%，其中37.3%的肿瘤大小小于1厘米。有20个肿瘤为微小癌。已知只有13.7%的病例有淋巴结转移，43%的癌症发生在50岁以下的女性中。整个年龄范围内的结果印证了最初的期望，即筛查和早期诊断将影响女性乳腺癌的预后。
