Lobular Neoplasia Diagnosed at Core Biopsy Does Not Mandate Surgical Excision

Based on the reviewed literature, it is difficult to reach a firm evidence-based conclusion regarding optimal management of LIN diagnosed at CNB. Associated high-risk lesions increase the risk of upgrade, but there are no mammographic predictors. The available retrospective literature suggests that some cases of LIN are associated with higher-risk lesions identified on surgical excision but does not support routine excision for all patients.
