Our guiding philosophy is to preserve as much of the breast as possible.

Lumpectomy – A breast-conserving procedure for a localized breast cancer involves the surgical removal of the lump and a small amount of tissue surrounding the lump.

Partial Mastectomy – Another breast-conserving procedure involving a wider excision to remove a greater amount of tissue around the lump. A quadrantectomy removes approximately one-fourth of the breast.

Simple Mastectomy – Removal of the breast tissue, leaving the underlying chest muscle intact.

Modified Radical Mastectomy – A simple mastectomy combined with auxiliary lymph node removal.

Breast Reconstruction – Our surgeons utilize innovative oncoplastic techniques during breast cancer surgery to minimize scarring and preserve the shape and size of the breast as much as possible. If a masectomy is required, plastic surgeons offer various options to reconstruct the breast such as tissue expanders and implants, including:
