Breast Symmetry After Lumpectomy
Breast symmetry issues are common after a lumpectomy. There are several surgical approaches that can be used to improve overall breast symmetry:
Breast reduction of the unaffected breast:
Since the lumpectomy removes breast tissue on the cancer side, the affected breast often ends up smaller than the other breast. Reducing the size of the unaffected breast can therefore improve symmetry. This can be combined with fat grafting on the lumpectomy side to restore volume and correct any contour deformity at the lumpectomy site.
Breast lift (mastopexy) of the unaffected breast:
When a lumpectomy is performed in the upper breast it can raise the position of the nipple-areola. If the overall size of the breasts is still close, symmetry can be improved by performing a lift of the unaffected breast.
Enhancement of the lumpectomy breast:
Fat grafting is becoming widely used in breast surgery. Fat is liposuctioned from one part of the patient's body, purified and then injected into the breast to restore volume and correct the contour deformity created by the lumpectomy. Studies have also shown that once the injected fat "takes", it can also help improve the thickness and quality of radiation-damaged tissue and skin. Since most lumpectomy patients also have radiation, fat grafting can therefore be quite beneficial.
Some surgeons prefer to use a small implant instead of fat grating to restore volume. This can work very well in patients who have not had radiation. However, the risk of future implant-associated complications, particularly hardening (known as capsular contracture), is much higher in patients who have had radiation.
Enhancement of both breasts:
Implants can be used to enhance the size of both breasts. Usually this will involve placing a larger implant in the lumpectomy side. Again, it is very important to realize that there is an increased risk of implant-related problems (particularly capsular contracture) in patients who have radiation therapy after their lumpectomy.
