48 Chapter 3 CONCLUSION Although breast cancer surgery is increasingly focusing on less extensive procedures, the need for standard removal of the PF during mastectomy has not frequently been questioned nor studied. The studies described are heterogenic with relatively small patient groups. Based on the current literature, PF preservation seems to be an oncologically safe procedure, especially when the tumor is located at a safe distance from the PF. Preservation of the PF might decrease the postoperative seroma formation. It may also decrease bleeding complications, infection rates, and the rates of implant extrusion while improving cosmetic outcomes. However, the current literature lacks evidence on these topics. More studies are required to systematically assess all relevant outcomes.
