Terminal duct lobular unit

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 linking involution of terminal duct lobular units (TDLU), the structures from which most breast cancers arise (3), and MD have provided important clues (4, 5). TDLU involution, a normal process of aging, is characterized by a reduction in the number and size of TDLUs and their secretory substructures called acini (3). Likewise, MD decreases Results.—Terminal duct lobular unit was seen in 17 GUNs (26%).

Extensive mammographic density (MD), a well‐established breast cancer risk factor, is a radiological representation of stromal and epithelial breast tissue content. In studies conducted predominantly among Caucasian women, histologic measures of reduced terminal duct lobular unit (TDLU) involution have been correlated with extensive MD, but independently associated with breast cancer risk

(A) Women with predominantly type 1 lobules were significantly older than women with predominantly type 2 lobules (manual method: p<0.01; automated method: p=0.01). 2018-02-01 · Lobular neoplasia is a term that includes both ALH and classic LCIS, the distinction being only the percentage of the terminal ductal lobular unit involved (greater for LCIS than ALH). Risk of breast cancer—invasive and ductal carcinoma in situ (DCIS)—is increased for both, approximately a four- to fivefold increased risk for ALH and eight- to ninefold increased risk for LCIS, with both terminal duct lobular unit answers are found in the Taber's Medical Dictionary powered by Unbound Medicine.

The collecting duct has several branches, which ends in a terminal ductal-lobular unit (TDLU), the basic functional and histopathological unit of the breast. The TDLU is composed of a small segment of the terminal duct and a cluster of ductules, which are the effective secretory units.

The terminal ductal lobular units (TDLUs) are the functional units of the breast. The TDLU consists of the extralobular terminal ducts and intralobular terminal ducts. The intralobular terminal ducts form the central space of the lobule and have multiple outpouchings called acini or ductules.

The TDLU is the functional unit of the breast. TDLUs consists of: extralobar terminal duct (ETD) which attaches the lobule to the ductal system; intralobar terminal duct (ITD) continues the duct system into the lobule clusters of 10-100 sac-like acini that open into the ITD. Acini and the terminal duct are the source of milk production.
