Introduction Invasive lobular carcinoma (ILC) is the most common ‘special’ type of breast cancer and presents with a dis- tinct morphology and clinical behaviour compared with invasive carcinoma of no special type (IC-NST). Breast carcinomas are often divided into 2 main types: invasive ductal carcinoma and invasive lobular carcinoma, based on how they look under the microscope. Staging is based on several factors, including the size of the tumor, where it’s located and how far it has spread: Stage 1: The tumor. Breast cancers usually are epithelial tumors of ductal or lobular origin. Loss of E-cadherin expression due to mutation of the CDH1 gene is a characteristic feature of invasive lobular breast cancer (ILBC).
