Answer:
The fatty component of the breast is about 50% (reduction specimens), contrary to popular belief, this percentage increases with age and body mass and breast volume. The amount of fat which can be extracted represents about 20% of the breast tissue which needs to be removed to obtain the appropriate breast volume. Liposuction has been shown in a University of Brussels study not to induce calcifications which can be confused with breast cancer. If calcifications do occur they are more round and scattered than those seen with breast cancer. Liopsuction performed with a blunt cannula does not remove parenchyma, and therefore the risk of unknowingly removing a specimen which might contain a malignancy is low. Suction alone can be used for congenital asymmetry, or post-reduction asymmetry, or enlargement.
