What kind of surgery is the best way to remove the breast tumor and a small amount of surrounding normal tissue?

Lumpectomy: A lumpectomy is what you describe. This may not be an option for all breast tumors, though. It is best to discuss surgical options with your surgeon. Depending on the type of tumor, you may also need to consider radiation therapy after the lumpectomy. Ask your surgeon if lumpectomy would be a possibility.

Oncoplastic Surgery: The goal of breast conserving surgery is tumor removal w/clear margins. The "art" of this operation involves removing just enough tissue: too much and you lose the aesthetic benefit of breast conservation; too little necessitates a 2nd operation (re-excision lump-x), likewise worsening the aesthetic result. Oncoplastic surgery incorporates plastic surgical techniques to achieve the best result.

Lumpectomy: A lumpectomy removes a breast tumor and a small rim of normal tissue in order to obtain negative margins. A lumpectomy should be performed without causing too much deformity to the breast (oncoplastic lumpectomy).
