What is the definition or description of: lumpectomy?

Excisional biopsy: Lumpectomy is an excisional biopsy usually used when applied to removing a breast tumor or cancer - just an easier word to say than----partial mastectomy ---that is the billing coding term used for the same but that would confuse and scare patients. But as it applies to the surgeon - the key is the margins are addressed for cancer involvement and must be negative.

Removal of lump: A lumpectomy means removal of a breast lump. It frequently is used in relation to removal of breast cancer. However it can be generalized to removal of other lumps or imaging abnormalities also. Other terminology such as excision, wide excision or a partial mastectomy usually may mean the same thing. If it is done for breast cancer frequently it needs to be supplemented by radiation therapy.

Cancer Operation: A lumpectomy is a breast cancer operation where the cancer is removed with a margin of normal breast around it.
