Surgical removal of part of the breast

Medical intervention

Quadrantectomy Specialty Surgical oncology [edit on Wikidata]

A **quadrantectomy**, also referred to as a segmental or partial [mastectomy](/source/Mastectomy), is a [breast-conserving surgery](/source/Breast-conserving_surgery) for [breast cancer](/source/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](/source/Tumor).[1][2] This procedure is an alternative to a radical or simple mastectomy, in which an entire breast is removed.[2]

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.[3]
