Many patients express a desire for "natural breast reconstruction." This requires the use of tissue harvested from another part of the body, typically the abdomen or the buttocks. While flap procedures are more involved than breast implant placement, there are benefits that make this option appealing. A significant benefit is that the tissue transferred from one area to the breast will feel like natural breast tissue. This is because the fatty tissue has the same makeup. Another advantage of flap reconstruction procedures is that the appearance of the breasts will change with age in the same way. This is particularly relevant for women who undergo unilateral mastectomy and want their breasts to age symmetrically.
