cells completely filling the lumina. The overall lobular architecture is preserved.
It is frequently multifocal (90% in some series) and bilateral. It seldom becomes
invasive; however there is an increased risk of infiltrating ductal adenocarcinoma.;
Alternative definition : NCI-GLOSS: A condition in which abnormal cells are found in the lobules of the breast.
Lobular carcinoma in situ seldom becomes invasive cancer; however, having it in one
breast increases the risk of developing breast cancer in either breast.;
