Mastectomy versus Lumpectomy for Invasive Breast Cancer

This chapter provides a summary of a landmark study in surgery. Do all women with invasive breast cancer require a total mastectomy, or is breast conserving therapy (i.e., lumpectomy) appropriate in some women? Starting with that question, it describes the basics of the study, including funding, study location, who was studied, how many patients, study overview, study intervention, follow-up, endpoints, results, and criticism and limitations. The chapter briefly reviews other relevant studies and information, discusses implications, and concludes with a relevant clinical case.
