MRI Use and its Impact on Surgical Decision Making in Invasive Lobular Carcinoma of the Breast

Abstract

Background: Invasive lobular carcinoma (ILC) accounts for approximately 10% of all breast cancers. It is more likely to be multifocal, bilateral and mammographically occult than invasive ductal carcinoma. MRI is sometimes warranted to assess the extent of disease but its routine use in ILC is controversial. The aim of this study was to assess MRI use and its impact on surgical decision making in a modern cohort of Irish women with a diagnosis of ILC.
