CHANGES IN THE SITUATION

(a) Breast: Deviations may be: +Uni or bilateral sides (“shield-shielded mates”). Towards up. +Down. (b) The nipple: +Supraareolar nipple: +Lateralized in the areola. +Exoareolar nipple: Outside the areola (“supramarary nipple”).

ALTERATIONS OF THE FORM

(a) Breast: conical/pyriform, flattened/discoid, cylindrical, pediculate, pendulous. (b) Nipple: Prominent, flattened, retracted/umbilicated, pediculated, bipartite. (c) Of the areola: Prominent or withdrawn.

SIZE ALTERATIONS
