BREAST
ENHANCEMENT : BREAST ENLARGEMENT
Breasts vary in both size and shape,
and their external appearance is not predictive of their internal anatomy or
lactation potential. The shape of a woman’s breasts is in large part dependent
on their support, which primarily comes from the Cooper's ligaments, and the
underlying chest on which they rest. The breast is attached at its base to the
chest wall by the deep fascia over the pectoral muscles. On its upper surface
it is given some support by the covering skin where it continues on to the upper
chest wall. It is this support which determines the shape of the breasts. In
a small fraction of women, the frontal milk sinuses (ampulla) in the breasts
are not flush with the surrounding breast tissue, which causes the sinus area
to visibly bulge outward.
