The Breast is a prominent gland located on the left and right sides of the chest of a primate. Varying in sizes and shapes, the breast is most notable for possessing the ability to secrete milk to feed infants.
Both men and women develop breasts, however, at puberty, female gender hormones promote breast development, while male gender hormones do not, as a result, women's breasts become far more prominent than those of men when reaching adulthood.
Biologically, the breast is a gland with the intended purpose of producing milk to feed an infant child. Each breast has a nipple located at its peak. Each nipple is surrounded by a patch of coloured skin called the areola, which is usually coloured the same colour as the nipple. The areola serves to protect the skin around the nipple during Breastfeeding. Within the breast are 15 to 20 lobes which produce milk, these are connected to various ducts that in turn connect to openings in the nipple.
