Objective: To know the techniques of BCS and OPS and its outcomes and compare between BCS 
and OPS and known which of them is best as regard pathological surgical margins; wound 
complications and patient satisfaction. Methodology: This study is a prospective study. It was 
performed in the period from January 2018 to January 2020. This study was conducted on patients 
from Minia University Hospital and Minia Oncology Center. Patients enrolled in this study were 
scheduled for conservative breast surgery and oncoplastic breast surgery latissimus dorsi (LD) flap.
Results: Our study included 20 patients with breast cancer who underwent conservative breast 
surgery or oncoplastic breast surgery latissimus dorsi (LD) flap .Only 5% of total patients has positive 
free margin and also 5% developed post-operative wound complication. Conclusion: oncoplastic 
BCS can achieve satisfactory results regarding the final aesthetic appearance and tumor control. The 
latissimus dorsi flap not only is a safe and cosmetic method of reconstruction in this clinical scenario 
but also is associated with favorable patient-reported outcomes.
