(1)Excision volume compared to the total breast volume was estimated by using the photograph of preoperative marking of a partial resection area.
(2)Breast density was classified into four categories based on the Breast Imaging Reporting and Data System (BI-RADS).
(3)The cosmetic result was evaluated based on photographs taken one year after the operation.
*The cosmetic result of 2 years after the operation was down to be good.
