Boobs

Boobs are a colloquial term for the breasts, the paired structures on the chest that can produce milk in individuals with functioning mammary tissue. An anatomical description notes that each breast contains glandular tissue organized into lobes and lobules that synthesize milk, milk ducts that carry milk to the nipple, and supportive tissue composed of fat and connective tissue. The nipple protrudes from the center of the pigmented areola, and the overall size, shape, and firmness of a breast vary widely among individuals.

Development and variation: During puberty, hormonal changes—particularly estrogen and progesterone—drive breast development. Size and shape range from petite to very large and are influenced by genetics and body fat. After pregnancy, lactation can enlarge the glands and milk production begins, and menopause can reduce glandular tissue and elasticity.

Function and lactation: The primary biological function is nourishment of offspring through lactation. Human milk provides nutrients and antibodies and is produced in the alveolar glands; milk travels through ducts to the nipple. Not all people with breasts breastfeed; lactation requires hormonal signals and mechanical nipple stimulation.

Health considerations: Common benign conditions include fibrocystic changes and benign lumps. Breast cancer is a significant health concern and screening recommendations vary by age and risk, typically involving imaging such as mammography. If a new lump, persistent pain, discharge, or skin changes are noticed, medical evaluation is advised.

Cultural and social context: Breasts carry sexual, aesthetic, and cultural meanings that vary across societies and over time. Public health and medical discussions emphasize safety, body autonomy, and respect.
