Cancer happens when cells in the body replicate without restriction. Usually, our bodies do a pretty good job of regulating the production of new cells to replace those that have died out. However, problems i.
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 mammary gland is a distinguishing feature of mammals and its primary role is to produce milk to nourish offspring Figures 1. In humans, the breast has a multitude of further roles including being a major female sexual characteristic and a key part of female body image.

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.
It is important for women to become familiar with the normal anatomy and physiology function of their breasts so that they can recognize early signs of possible abnormalities. This section outlines basic information on breast composition, development, and typical changes from puberty to pregnancy to menopause. A layer of fatty tissue surrounds the breast glands and extends throughout the breast.
If you thought that viral image claiming to show a woman's flower-shaped milk ducts looked weird, you would be correct. That's because the image isn't an accurate portrayal of a woman's mammary glands. In reality, women's milk ducts look nothing like that image.
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.
