Anatomical terminology [edit on Wikidata]

The breast is an organ on the mid to upper chest area. It is just below the shoulders near the center of the upper chest region of humans and other primates. Humans have two breasts. Both boys and girls have breasts at birth. During puberty, the breasts on women grow larger and more visible. The breasts have glands that produce milk. Breastfeeding is when a mother feeds her baby with milk from her breasts.

Men also have breasts. They are built the same way as those of women, but are usually smaller, Men cannot use their breasts for breastfeeding. Their breasts will usually not produce milk, but might become larger and produce milk during some diseases or with some hormonal medical treatments.^[2]
