Breast carcinoma continues to be the most common cause of death due to malignancy for women in Canada. The Screening Mammography Program of British Columbia, the first provincial screening program in Canada, was established in 1988 with funding from the Ministry of Health to diagnose the disease as early as possible. The program has grown rapidly, increasing from 7,100 examinations in a pilot project in 1988 to 89,390 examinations between April 1, 1992 and March 31, 1993 for a cumulative total of 201,937 examinations of 128,325 women, and it now offers free screening mammography throughout the province. The program has maintained quality control standards and low cost per mammogram while developing different operational models for the differing requirements of the various areas of the province. Similar proportions of women older or younger than age 50 have favourable characteristics such as small size of tumor (median: 15 to 16 mm) and negative lymph nodes (86% to 89%).
乳腺癌仍然是加拿大女性因恶性肿瘤死亡的最常见原因。不列颠哥伦比亚省的乳腺钼靶筛查项目是加拿大首个省级筛查项目，于1988年在卫生部的资助下设立，旨在尽早诊断该病。该项目发展迅速，从1988年试点项目中的7100次检查增加到1992年4月1日至1993年3月31日期间的89390次检查，累计对128325名女性进行了201937次检查，现在该项目在全省范围内提供免费的乳腺钼靶筛查。该项目在为该省不同地区的不同需求开发不同运营模式的同时，保持了质量控制标准和每次钼靶检查的低成本。50岁及以上或以下的女性中，具有肿瘤体积小（中位数：15至16毫米）和淋巴结阴性（86%至89%）等良好特征的比例相似。
