lobular neoplasia  listen  (LAH-byoo-ler NEE-oh-PLAY-zhuh)

  A condition in which abnormal cells are found in the lobules (glands that make milk) of the breast. This condition rarely becomes cancer. However, having lobular neoplasia in one breast increases the risk of breast cancer in either breast. Types of lobular neoplasia include atypical lobular hyperplasia and lobular carcinoma in situ (LCIS). Also called LIN and lobular intraepithelial neoplasia.
