Before you learn how a breast augmentation with a breast lift can help to correct breast appearance, it is important that you understand the underlying anatomy. The breasts are composed of different types of tissue known as glandular, fatty, and fibrous tissue, which lie over the pectoralis muscle, along the chest wall. The glandular tissues are composed of lobules and milk ducts. Together, lobules and milk ducts are responsible for producing and transporting milk to the nipple, respectively during lactation. The glands within the breast are surrounded by a layer of fatty tissue that gives the breast its shape and soft form. Suspensory ligaments, which are made of fibrous, or connective tissue, are intertwined amongst the breast glands and milk ducts. These suspensory ligaments attach the breast to the chest wall and allow it to remain suspended, but move freely with the body.
