Mastectomy Linked to Significant Reduction in Breast Cancer Mortality, New Study Finds
SÃO PAULO, BRAZIL – October 9, 2025 – women undergoing mastectomy experience a 35% decrease in the risk of death from breast cancer, according to a recent study highlighting the potential life-saving benefits of the procedure. A concurrent oophorectomy (removal of the ovaries) demonstrated an even greater impact, reducing mortality risk by 42%. Both interventions were also shown to lower the likelihood of cancer recurrence or new tumor progress by 32%.
The findings, which remained consistent even after accounting for factors like tumor type, lymph node involvement, and age at diagnosis, offer crucial insights for personalized breast cancer treatment, particularly for those with aggressive subtypes like triple-negative breast cancer. While these results underscore the potential of proactive surgical interventions, access to the genetic testing needed to identify patients who would benefit moast remains a significant barrier in Brazil.
The study reinforces the importance of tailored treatment strategies and the critical role of genetic counseling for young women diagnosed with breast cancer. Considerations extend beyond medical outcomes to encompass quality of life, family planning desires, the potential for early menopause, and body image concerns.
Currently, genetic mapping is not universally available to women in Brazil. despite laws mandating testing in some states, access through the public healthcare system (SUS) is limited.Genetic tests are available in the private sector, having been accessible for over 15 years.
Dr. Maira Caleffi, a breast specialist, emphasizes the need for wider access to genetic testing to ensure all patients can benefit from informed treatment decisions. The research suggests a proactive approach, guided by genetic counseling, can considerably improve outcomes for those facing a breast cancer diagnosis.
