The basic units of the breast are the terminal duct lobular units (TDLUs), which produce the fatty breast milk. They give the breast its offspring-feeding functions as a mammary gland. They are distributed throughout the body of the breast. Approximately two-thirds of the lactiferous tissue is within 30 mm of the base of the nipple.

Terminal duct lobular unit

There is evidence to suggest that ductal and lobular breast cancer arises in the terminal duct/lobular unit (TDLU). Terminal duct lobular units (TDLUs) are the anatomical structures of the breast that produce milk and represent the predominant histological source of breast cancers.1 During normal aging the number and size of TDLUs and acini (epi-thelial substructures within TDLUs) are reduced through a process known as TDLU involution. Reduced levels of TDLU Background: Manual qualitative and quantitative measures of terminal duct lobular unit (TDLU) involution were previously reported to be inversely associated with breast cancer risk. We developed and applied a deep learning method to yield quantitative measures of TDLU involution in normal breast tissue.
