High-risk breast lesions, which comprise benign lesions and in situ carcinomas (lobular
carcinoma in situ and ductal carcinoma in situ), are clinically, morphologically, and …

OBJECTIVE. Atypical ductal hyperplasia (ADH), atypical lobular hyperplasia (ALH), and
lobular carcinoma in situ (LCIS) are among high-risk lesions that have been previously …

The vast majority of image-detected breast abnormalities are diagnosed by percutaneous
core needle biopsy (CNB) in contemporary practice. For frankly malignant lesions …

More than 10% of breast biopsies performed based on findings at mammography yield
highrisk lesions (HRLs). 1 HRLs refer to a group of heterogeneous lesions that can be …

Background Based on modern series demonstrating low upgrade rates for pure lobular
neoplasia (LN) diagnosed on core needle biopsy (CNB), our institution no longer …

Benign and atypical lesions associated with breast cancer risk are often encountered in core
needle biopsies (CNBs) of the breast. For these lesions, the rate of “upgrade” to carcinoma …

Pathologists frequently encounter non‐malignant histological findings in percutaneous core
needle biopsies (CNB s). Standards for the management of patients with lesions such as …

BACKGROUND Breast cancer risk estimates for atypical lesions are based primarily on case‐
control studies of patients with open biopsies. The authors report the cumulative breast …

Benign breast diseases, which are commonly seen in clinical practice, have various clinical
presentations and implications, as well as management strategies. This article describes …

Atypical hyperplasia (AH) and lobular carcinoma in situ (LCIS) are nonmalignant breast
lesions that confer a 4-to 10-fold increased risk for breast cancer in women. Often, AH and …
