Breast

The breast is one of two prominences located on the upper ventral region of a primate 's torso. Both females and males develop breasts from the same embryological tissues. In females, it serves as the mammary gland , which produces and secretes milk to feed infants. At the ends of the ducts are lobules , or clusters of alveoli , where milk is produced and stored in response to hormonal signals. Humans are the only animals with permanent breasts. At puberty , estrogens, in conjunction with growth hormone , cause permanent breast growth in female humans. This happens only to a much lesser extent in other primates—breast development in other primates generally only occurs with pregnancy. Along with their major function in providing nutrition for infants, female breasts have social and sexual characteristics. Breasts have been featured in ancient and modern sculpture, art, and photography. They can figure prominently in the perception of a woman's body and sexual attractiveness. A number of cultures associate breasts with sexuality and tend to regard bare breasts in public as immodest or indecent. Breasts, especially the nipples, are an erogenous zone.

Each breast contains 15 to 20 lobes of glandular tissue, arranged like the petals of a daisy. The lobes are further divided into smaller lobules that produce milk for breastfeeding. Small tubes, called ducts, conduct the milk to a reservoir that lies just beneath your nipple. After skin cancer, breast cancer is the most common cancer diagnosed in women in the United States.
