A relatively large number of women in their 40s with high-density breasts, in which it can be difficult to detect lesions, are encountered in mammography cancer screenings in Japan. Here, we retrospectively investigated factors related to breast density. Two hundred women (40-49 years old) were examined at the screening center in our hospital. Multivariate analysis showed that factors such as small abdominal circumference, high HDL cholesterol, and no history of childbirth were related to high breast density in women in their 40s undergoing mammography. Other non-mammographic screening methods should be considered in women with abdominal circumferences < 76cm, HDL-C ≥ 53mg/dl, and no history of childbirth, as there is a strong possibility of these women having high-density breasts that can make lesion detection difficult.
在日本的乳腺钼靶癌症筛查中，会遇到相对较多40多岁、乳房密度高的女性，在这类乳房中很难检测到病变。在此，我们回顾性研究了与乳房密度相关的因素。在我院筛查中心对200名40至49岁的女性进行了检查。多变量分析表明，腹围小、高密度脂蛋白胆固醇高以及无分娩史等因素与接受乳腺钼靶检查的40多岁女性的高乳房密度有关。对于腹围<76cm、高密度脂蛋白胆固醇≥53mg/dl且无分娩史的女性，应考虑采用其他非乳腺钼靶筛查方法，因为这些女性极有可能乳房密度高，从而难以检测到病变。
