What supports the breast and contributes to its shape?

Cooper ligaments, also known as suspensory ligaments of the breast, play a crucial role in providing structural support and maintaining the shape of the breast. These ligaments are connective tissue structures that extend from the breast skin to the underlying pectoral fascia, helping to tether the breast tissue in place. Their tension and integrity are significant for the overall aesthetic appearance of the breast, as they help prevent sagging and maintain firmness.

While adipose tissue contributes to the volume and general softness of the breast, it does not provide the same level of structural support that Cooper ligaments offer. Similarly, muscle fascia relates to the muscles in the chest but is not directly responsible for supporting breast tissue. Skin structure may influence the external appearance of the breast but does not contribute to the internal support mechanisms. Therefore, the function of Cooper ligaments in connecting breast tissue to underlying structures and maintaining shape makes this option the most appropriate choice.
