The World Health Organization's Pathology and Genetics of Tumours of the Breast and Female Genital Organs states "invasive breast carcinoma is a group of malignant epithelial tumours characterized by invasion of adjacent tissues and a marked tendency to metastasize to distant sites. Subsequent invasive carcinomas are 3x more likely to be lobular (than in the general population) but most commonly are of no special type Clinical and histologic features that may identify patients with LCIS that are likely to develop invasive breast cancer have not been consistently identified.

Invasive lobular carcinoma of the breast is the most common ‘special’ morphological subtype of breast cancer, comprising up to 15% of all cases. Measure and report the actual distance of both invasive and in situ carcinoma Angiolymphatic invasion Indicate if confined to tumor mass, outside tumor mass or in dermis (Extensive DCIS is not currently felt to be a significant predictor of behavior) Results of special studies performed for diagnosis Results of prognostic special studies performed. LCIS is discussed on a€different page. Measurements can be made by marking the tumor on microscopy, and then measuring between the markings, which may overlap between multiple slides as shown. 9-11 These findings are nonspecific, however, and may be found in invasive ductal carcinoma , invasive lobular carcinoma , and many benign processes. Cancer is the second-leading cause of death in people in the United States, and breast cancer is the most common malignancy in women, estimated to account for 27% of expected new cancer cases in 2009. The pathologic stage for invasive lobular carcinoma is based on the TNM staging system, an internationally recognized system originally created by the American Joint Committee on Cancer. The breast contains lobes where milk is made. Invasive lobular carcinoma is more often multicentric and bilateral (10-15%). 2 Images 3 IHC 4 See also 5 References General.
