NCIt definition : An adenocarcinoma of the breast arising from the lobules. This is a relatively uncommon
carcinoma, represents approximately 10% of the breast adenocarcinomas and is often
bilateral or multifocal.;
Alternative definition : NCI-GLOSS: Cancer that begins in the lobules (the glands that make milk) of the breast.
Lobular carcinoma in situ (LCIS) is a condition in which abnormal cells are found
only in the lobules. When cancer has spread from the lobules to surrounding tissues,
it is invasive lobular carcinoma. LCIS does not become invasive lobular carcinoma
very often, but having LCIS in one breast increases the risk of developing invasive
cancer in either breast.;
