For example, it appears that the axillary mound is more likely to contain accessory ductal tissue than any of the other accessory fatty mounds along each mammary chain, perhaps more commonly serving as a nidus for breast cancer formation, though incidence of tumor formation in the other vestigial breast mounds has not been established.
Accessory breasts, also known as polymastia, supernumerary breasts, or mammae erraticae, is the condition of having an additional breast. These extra breasts may appear with or without nipples or areolae. The condition, a form of atavism, is most commonly observed in males and is generally harmless, often going untreated.
The Triple Nipple Club is a documentary shown on Channel 4 which explored the biological mystery of the supernumerary nipple. [9] First broadcast on 2 January 2008, it was directed and produced by Dan Louw and commissioned as part of Channel 4's First Cut series. [10]
Accessory breast tissue has a classification system depending on how the condition presents in the individual. [8] Separate terms are used for different combinations of the presence of nipple, areola, or glandular tissue. The most common presentation, termed polythelia, is where only the nipple is present without the areola and glandular tissue ...
A mammary gland is an exocrine gland in humans and other mammals that produces milk to feed young offspring.Mammals get their name from the Latin word mamma, "breast".The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants (for example, cows, goats, sheep, and deer), and the dugs of other animals (for example, dogs ...
Lactiferous ducts are ducts that converge and form a branched system connecting the nipple to the lobules of the mammary gland.When lactogenesis occurs, under the influence of hormones, the milk is moved to the nipple by the action of smooth muscle contractions along the ductal system to the tip of the nipple.
A mammary ridge, or crest, usually stops growing at eight weeks and its length is regressed starting at the caudal end and extending cranially, [1] so that what remains is a round, ectodermic placode where the axilla develops. When shortening of the mammary crest is complete, the structure remains prominent in the areas where the mammary glands ...
The en bloc removal of the breast tissue became known as the Halsted mastectomy before adopting the title "the complete operation" and eventually, "the radical mastectomy" as it is known today. [ 5 ] Radical mastectomy was based on the medical belief at the time that breast cancer spread locally at first, invading nearby tissue and then ...
