Description

As is the case in many other countries, mammography is currently used in Japan for breast cancer screening. However, as it cannot detect lesions in dense breasts such as those of young women, ultrasound (US) imaging is used for this purpose. Although there have been numerous reports of US screening, the results obtained using the recall criteria stipulated by the Japan Association of Breast and Thyroid Sonology (JABTS) has not yet been reported. We have performed US screening based on the JABTS guidelines for three years. Technologists perform the examinations, and physicians select recall cases on the basis of these criteria. So far there have been 17,089 attendees, of whom 90% were less than 50 years old. The recall rate was 3.6% (616/17,089). The results of further examinations were confirmed in 452 of these 616 recalled women, and breast cancer was detected in 48 (0.28%) of them. Cancer was detected early in 37 (80.5%) of these 48 cases. Mammography was unable to detect cancer in 16 (43%) of the cases. Although the high recall rate of US screening has been mentioned previously, we wish to emphasize that US breast cancer screening is effective, particularly in younger women. Furthermore, the reasonable recall rate ensures that a high quality of detection is maintained.
