She chairs the breast service at MSKCC and has been president of the Society of Surgical Oncology. Her work continues on tailoring surgery to response after neoadjuvant therapy.","asOf":"2026-09-10","links":[{"label":"PubMed","url":"https://pubmed.ncbi.nlm.nih.gov/?term=Morrow%20M%5BAuthor%5D%20breast%20margins"}],"tags":["breast","surgery","de-escalation"],"related":[],"cancers":["breast-hr-positive","tnbc","breast-her2-positive"],"sections":[],"technologies":["sentinel-node"],"targets":[],"drugs":[],"companies":[],"institutions":["mskcc","sso"],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"role":"Chief, Breast Service, Department of Surgery, Memorial Sloan Kettering Cancer Center","institutionId":"mskcc","specialisms":["Breast surgery","Surgical margins","Axillary management","Surgical de-escalation"],"profiles":[{"label":"PubMed","url":"https://pubmed.ncbi.nlm.nih.gov/?term=Morrow%20M%5BAuthor%5D%20breast%20margins"}],"papers":[{"title":"Society of Surgical Oncology-American Society for Radiation Oncology consensus guideline on margins for breast-conserving surgery with whole-breast irradiation in stages I and II invasive breast cancer","journal":"JCO","year":2014,"doi":"10.1200/JCO.2013.53.3935"},{"title":"Surgeon recommendations and receipt of mastectomy for treatment of breast cancer","journal":"JAMA","year":2009,"doi":"10.1001/jama.2009.1450"}]},"route":"/people/monica-morrow/","neighbours":{"cancer":[{"id":"breast-her2-positive","kind":"cancer","name":"HER2-positive breast cancer","route":"/cancers/breast-her2-positive/"},{"id":"breast-hr-positive","kind":"cancer","name":"HR-positive / HER2-negative breast cancer","route":"/cancers/breast-hr-positive/"},{"id":"tnbc","kind":"cancer","name":"Triple-negative breast cancer (TNBC)","route":"/cancers/tnbc/"}],"technology":[{"id":"sentinel-node","kind":"technology","name":"Sentinel lymph node biopsy","route":"/technologies/sentinel-node/"}],"institution":[{"id":"mskcc","kind":"institution","name":"Memorial Sloan Kettering Cancer Center","route":"/institutions/mskcc/"},{"id":"sso","kind":"institution","name":"Society of Surgical Oncology","route":"/institutions/sso/"}]}}
