Hi Erinn - Most women's breasts are made up of both fat tissue and gland tissue. The gland tissue is usually too hard (in consistency) to remove with liposuction so breast reduction by liposuction is limited in the amount of volume that can be removed (since it can only remove the excess fat tissue, not gland).
Breast reduction surgery can be completed using several different methods and several different scar patterns. The common elements between each type of breast reduction surgery are reducing the size, elevating and reshaping the breast. Elevating and reshaping the breast cannot be done by liposuction alone.
Some women do require liposuction in conjunction with breast reduction to get the most aesthetically pleasing result - the rolls of fat at the sides of the breasts, under the armpits are treated with liposuction as these areas are not addressed by breast reduction techniques.
