Invasive lobular carcinoma (ILC) is breast cancer arising from the lobules of the mammary glands. [1] It accounts for 5–10% of invasive breast cancer . [ 2 ] [ 3 ] Rare cases of this carcinoma have been diagnosed in men (see male breast cancer ).
Lobular carcinoma is a form of tumor which primarily affects the lobules of a gland. It is sometimes considered equivalent to "terminal duct carcinoma". [1] If not otherwise specified, it generally refers to breast cancer. Examples include: Lobular carcinoma in situ; Invasive lobular carcinoma
Carcinomas of mixed type will have a specialized pattern or lobular carcinoma in the majority (i.e. at least 50%) of the tumor and a non-specialized pattern in between 10 and 49% of the sample. Thus, such tumors will be called mixed invasive NST and special type or mixed invasive carcinoma NST and lobular carcinoma. [24]
Histopathology of invasive lobular carcinoma (ILC), next to lobular carcinoma in situ (LCIS). 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. Most of the risk relates to subsequent invasive ductal carcinoma ...
Those with ductal carcinoma in situ (in the mammary ducts) are at increased risk for developing true invasive breast cancer – around a third develop breast cancer within five years. [45] Lobular carcinoma in situ (in the mammary lobes) rarely causes a noticeable lump, and is often found incidentally during a biopsy for another reason. It is ...
The overall 5-year survival rate for both invasive ductal carcinoma and invasive lobular carcinoma was approximately 85% in 2003. [9] Ductal carcinoma in situ, on the other hand, is in itself harmless, although if untreated approximately 60% of these low-grade DCIS lesions will become invasive over the course of 40 years in follow-up.

SPC is considered invasive when the tumor nests have a characteristic jigsaw growth pattern with ragged and irregular margins with the loss of myoepithelial cells at the site(s) of invasion. [21] Rarely, invasive SPC occurs with nearby invasive carcinoma of NST, lobular carcinoma, cribriform carcinoma, or tubular carcinoma breast tumors. [3]
