Anatomy & Physiology of the Breast The breast is an organ whose structure reflects its special function: the production of milk for lactation (breast feeding). The epithelial component of the tissue consists of lobules, where milk is made, which connect to ducts that lead out to the nipple. Nov 01, · Internal Anatomy. The breast is composed of glandular ducts and lobules, connective tissue, and fat, with most of the benign and malignant pathology arising in the duct and lobular network (Figure 2). Specifically, most breast cancer is thought to originate in the terminal ductal lobular unit (TDLU). Figure 2.

Learn about breast anatomy so you can better understand breast cancer, be aware of anything unusual, & have better dialogue with your doctor. Breast anatomy and how cancer starts. The breast, like any other part of the body, consists of billions of microscopic cells. These cells usually multiply in an orderly fashion – new healthy cells continue to divide and replace the ones that have died. However, sometimes cells develop abnormalities .
