PRSA

Prsa is the plural form of the term used in several Slavic languages to denote the organ commonly referred to as the breast or chest. In medical and anatomical contexts, prsa refers to the paired structures on the upper front of the torso and to the region surrounding them. The word appears in everyday language as well as in clinical descriptions.

Anatomy and development: In humans, the breast comprises glandular tissue organized into lobes and lobules, milk ducts, adipose (fat) tissue, and connective tissue. The nipple and pigmented areola sit atop the breast. Size and shape vary widely due to genetics, body fat, hormonal status, and age. In males, glandular tissue is usually limited, leading to less prominent breasts, though some glandular development can occur.

Function and physiology: The primary biological function of the breasts is lactation to nourish offspring. Hormones such as estrogen, progesterone, and prolactin drive development during puberty and pregnancy. Milk is produced in the lobules and transported through ducts to the nipple; oxytocin triggers the let-down reflex during feeding.

Variation and health: Breasts show a wide range of sizes, shapes, and densities. Benign conditions such as fibrocystic changes and infections like mastitis can occur. In men, breast tissue can enlarge temporarily or persistently due to hormonal factors (gynecomastia). Breast cancer is a major health consideration; screening methods include self-exams, clinical examinations, and imaging such as mammography. Risk factors include age, genetics, and hormonal influences; treatment ranges from surgery to systemic therapies.

Cultural and social notes: Breasts are often discussed in the context of health, development, aesthetics, and sexuality. Attitudes toward prsa vary across cultures, while clinical discussions emphasize health, lactation support, and cancer risk awareness.
