More than 1 million women per year in the United States with benign breast biopsies are known to be at elevated risk for breast cancer (BC), with risk stratified on histologic categories of epithelial proliferation. Here we assessed women who had serial benign biopsies over time and how changes in the histologic classification affected BC risk.

连续良性活检中的乳腺癌风险和进行性组织学检查

在美国，每年有超过一百万名女性进行良性乳房活检的妇女罹患乳腺癌（BC）的风险较高，其风险按上皮增生的组织学类别进行分层。在这里，我们评估了随时间进行了一系列良性活检的女性，以及组织学分类的变化如何影响BC风险。
