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. The fatty tissue gives the breast a soft consistency. The glandular tissues of the breast house the lobules milk producing glands at the ends of the lobes and the ducts milk passages. Toward the nipple, each duct widens to form a sac ampulla.

Colostrum known colloquially as beestings ,  bisnings  or first milk is the first form of milk produced by the mammary glands of mammals including humans immediately following delivery of the newborn. Colostrum has especially high amounts of bioactive compounds compared to mature milk to give the newborn the best possible start to life. Colostrum also has a mild laxative effect, encouraging the passing of the baby's first stool , which is called meconium. This clears excess bilirubin , a waste-product of dead red blood cells, which is produced in large quantities at birth due to blood volume reduction from the infant's body and helps prevent jaundice.

Links are provided to move the reader to pages that present the content of specific nutrients in milk, important background information on the chemistry of milk carbohydrate lactose , fat, protein, and enzymes, and other topics that are covered in more depth in other sections of this website. The energy in milk comes from its protein, carbohydrate and fat content, with the exception of skim milk that has virtually no fat. The energy content of some milk varieties is shown in the Nutrient Content Tables.
NCI-funded researchers are working to advance our understanding of how to prevent, detect, and treat breast cancer. They are also looking at how to address disparities and improve quality of life for survivors of the disease. MRI magnetic resonance imaging , ultrasound , and clinical breast exams are also used to detect breast cancer, but not as routine screening tools. Ongoing studies are looking at ways to enhance current breast cancer screening options.
