A quadrantectomy, also referred to as a segmental or partial mastectomy, is a surgical procedure for breast cancer in which one quarter of breast tissue is removed along with muscles of the chest wall within a 2 to 3 centimeter radius of a tumor.〔(【引用サイトリンク】 title=Quadrantectomy )〕 This procedure is an alternative to a radical or simple mastectomy, in which an entire breast is removed. In a study that followed patients who underwent this procedure, it was found that only 9% of people who had a quadrantectomy experienced a relapse of the cancer. ==See also== *Mastectomy *Lumpectomy 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Quadrantectomy」の詳細全文を読む スポンサード リンク
