The Breast: Morphology, Physiology, and Lactation covers the mammary morphology and function related to endocrine physiology, as well as the pathophysiologic disorders, such as galactorrhea. Knowledge of the many hormones influencing the structure and function of the breast enables one to relate cyclic endocrine ovarian changes to symptoms of premenstrual mammary tension, parenchymal alterations, and breast neoplasia. This book is divided into nine chapters and begins with a description of the female breast development.

The human breast comprise several ductal systems, or lobes, which contain a small amount of fluid containing cells, hormones, proteins and metabolites. The complex physiology of these ducts is likely a contributing factor to the development of breast cancer, especially given that the vast majority of breast cancers begin in a single lobular unit. We examined the levels of total protein, progesterone, estradiol, estrone sulfate, dehydroepiandrosterone sulfate, and macrophages in ductal fluid samples obtained from 3 ducts each in 78 women, sampled twice over a 6 month period.

Author information: 1 Dr. The physiology of the nonlactating human breast likely plays a key role in factors that contribute to the etiology of breast cancer and other breast conditions. Although there has been extensive research into the physiology of lactation, few reports explore the physiology of the resting mammary gland, including mechanisms by which compounds such as hormones, drugs, and potential carcinogens enter the breast ducts.

Breast Anatomy and Basic Histology, Physiology, and Pathology As with all organ systems, an understanding of the anatomy, histology, and pathology of the breast leads to an enhanced ability to interpret imaging studies. Breast imaging primarily involves the assessment of the morphology of macroscopically visible breast structures. A basic understanding of the anatomy and histology of the breast, and of the complex underlying microscopic structures in which changes take place, is important for an understanding of the pathologic processes that occur. All are helpful for image interpretation.
