==Description==
The '''breast''' is the upper ventral region of an [[animal]]’s torso, particularly that of mammals, including [[human being]]s. The breasts of a [[female]] primate’s [[body]] contain the mammary glands, which secrete milk used to feed infants.
Both [[men]] and [[women]] develop breasts from the same embryological tissues. However, at [[puberty]], [[female]] sex hormones, mainly estrogen, promote breast [[development]] which does not occur in men. As a result, women's' breasts become far more prominent than those of men.
