(About 80% are invasive ductal carcinomas.) Invasive means that the cancer has “invaded” or spread to the surrounding breast tissues. Lobular means that the cancer began in the milk-producing lobules, which empty out into the ducts that carry milk to the nipple. Lobular neoplasia is considered pre-cancerous, and LCIS is an indicator (marker) for increased risk of developing invasive breast cancer in women. This risk extends more than 20 years.

Node Metastasis: Lobular tumors are often slower growing than ductal tumors, are more often estrogen and progesterone receptor positive (3, 4), have lower vascular endothelial growth factor expression (5), and more frequently have loss of E-cadherin (6, 7, 8). Ductal hyperplasia (also called duct epithelial hyperplasia) is an overgrowth of the cells that line the small tubes (ducts) inside the breast, while lobular hyperplasia is an overgrowth of cell lining the milk glands (lobules).

Stage-matched prognosis is better for patients with ILC than for those with IDC. Background. Invasive lobular breast cancer (ILC) is less common than invasive ductal breast cancer (IDC), more difﬁcult to detect mammographically, and usually diag-nosed at a later stage. Does delayed diagnosis of ILC affect survival? We used a national registry to compare outcomes of patients with stage-matched ILC and IDC. Methods.
