Brystene

Brystene, commonly referred to as breasts, are paired mammary glands located on the chest. They are a characteristic feature of human female anatomy but are present in all genders to varying degrees. In females, the breasts typically become prominent during puberty due to hormonal changes and play a central role in lactation, reproduction, and signaling.

Anatomy and structure: Each breast consists of glandular tissue arranged in lobes and lobules, ducts that channel milk to the nipple, fatty tissue that influences size and contour, and connective tissue that provides support. The pigmented area around the nipple is the areola. The amount of fatty tissue relative to glandular tissue determines individual size and shape, which can change with age, hormonal status, and body composition.

Function and development: The primary biological function of the breasts is milk production to nourish offspring. In pregnancy, hormonal changes stimulate the development of the glandular tissue and the ducts to prepare for lactation. Lactation is regulated by hormones such as prolactin and oxytocin, triggered by infant suckling.

Variation and health: Breast size and shape vary widely among individuals. Asymmetry between the breasts is common. Health issues may include benign conditions such as fibroadenomas or cysts, mastitis, and breast cancer, which can affect all people with breast tissue. Regular self-awareness and clinical screening according to local health guidelines are advised for early detection and management.

Cultural aspects: Breasts have various cultural meanings related to sexuality, gender, and body image, with norms and practices differing across societies.
