Younger women with nonmetastatic breast cancer who underwent breast-conserving surgery experienced similar overall survival (OS) as those who underwent mastectomy, according to latest study findings.  The findings, presented Dr Christine Pestana, a breast surgical oncology fellow at Atrium Health Levine Cancer Institute, during an American Society of Breast Surgeons Annual Meeting press briefing, indicate counselling patients regarding outcomes is key to reduce unnecessary morbidity from surgical procedures not indicated, given the increased use of mastectomy in this age group, though mastectomy rates are increasing in younger patients despite lack of data supporting improved survival. Researchers examined this association between surgical approach and survival among 591 women aged younger than 40 years, included in the Young Women’s Database at Levine Cancer Institute, who underwent surgical intervention for nonmetastatic invasive breast cancer between 2010 and 2019.
