  schema:description "Removing the whole breast, either for cancer or preventively in BRCA1/2 carriers, where bilateral risk-reducing mastectomy cuts breast cancer risk by 90% or more. For most early cancers, lumpectomy plus radiotherapy works as well, so mastectomy is chosen for large or multicentric tumours, inflammatory cancer, or patient preference."@en ;
