There is evidence to suggest that ductal and lobular breast cancer arises in the terminal duct/lobular unit (TDLU).

Terminal duct lobular units (TDLU), the histologic structures of the breast that are responsible for lactation, are the predominant source of breast cancers (1). TDLUs undergo various physiologic changes throughout the life of a woman (e.g., puberty, pregnancy, lactation, and menopause) and involute as women age (2, 3). TDLU

Structure of the Terminal Ductal Lobular Unit (TDLU) The adult gland forms a tree-like structure starting at the nipple and branching through the stroma to end in lobules. The lobules are the ultimate milk producing functional units of the breast. The milk is expulsed through the intra-lobular terminal ducts and the extra-lobular terminal ducts The lobules and acini of the terminal duct-lobular unit (TDLU), the basic functional unit of the breast, may become distorted and undergo expansion due to the abnormal proliferation of cells comprising the structure. These changes represent a spectrum of atypical epithelial lesions that are broadly referred to as lobular neoplasia (LN). Large duct system Conduit for milk Duct ectasia Papilloma, encapsulated papillary carcinoma, Terminal ductal lobular unit (TDLU) Luminal cells: Milk production; myoepithelial cells: Contraction for milk ejection Cysts (rupture), granulomatous lobular mastitis, lymphocytic mastopathy Epithelial hyperplasia, sclerosing adenosis, carcinomas Each nipple orifice communicated with a separate, nonanastomosing ductal system, which extended to the terminal duct lobular unit.

In 6 cases TDLU was seen in the section of base, while 6 cases had TDLU in the sections of papilla and 5 nipples had TDLU present in … Reduced involution of terminal duct lobular units (TDLU), the histologic source of most breast cancers, has been associated with higher MD and breast cancer risk.

Terminal duct lobular units (TDLU) are considered as the basic reacting unit in all neoplastic lesions arising from the breast. TDLU is the basic anatomic unit of breast parenchyma, studies revealed that it also exists in the nipple whose frequency is not widely researched.

TDLUs can be classified according to their complexity.
