Which breast layer is the premammary layer, composed of fat, connective tissue and contains Cooper’s ligaments?

• A. Subcutaneous layer
• B. Skin
• C. Retromammary space
• D. Mammary zone

Answer: (A)

The premammary layer is the subcutaneous tissue just under the skin. It’s made up of fat and connective tissue and contains Cooper’s ligaments (suspensory ligaments), which help anchor and support the breast to the skin and chest wall. This layer sits anterior to the glandular tissue of the breast. Behind the glandular tissue lies the retromammary space, which separates the breast from the pectoralis major and is not the premammary layer.
