Anatomically, a female's breasts do not contain any muscle but are composed of soft, glandular tissue. Breasts are composed of mammary glands, milk ducts, adipose tissue (fat tissue) and Cooper's ligaments. Mammary glands remain relatively constant throughout life. Fat tissue surrounds the mammary glands, and its volume will normally vary throughout life. Although the exact mechanisms that determine breast shape and size are largely unknown, the amount and distribution of fat tissue and, to a lesser extent, mammary tissue, cause variations in breast size, shape and volume. Some experts believe Cooper's ligaments, which are connective tissue with the breast, provide some support within breasts, but there's no agreement on whether they provide support or simply divide breast tissue into compartments.
