Objective: The objective of this study was to compare the advantages and disadvantages of patients undergoing either immediate or delayed breast reconstruction after mastectomy. Methods: This review was compiled using information from numerous web databases. Scientific articles were selected based on the inclusion criteria. Data were collected, organized, and summarized. Results: Mastectomy or breast removal is frequently performed as part of breast cancer treatment. Psychological issues following a mastectomy may get better for some patients after breast reconstruction. The most common type is immediate reconstruction, which preferably uses a nipple-sparing or skin-sparing mastectomy and implant-based reconstruction (but can also be autologous reconstruction). Delayed reconstruction is often performed using autologous tissue flaps or implant-based using either the definitive implant or temporary expanders. Conclusion: Immediate reconstruction creates better cosmetic outcomes, shorter overall costs, quicker recovery, higher quality of life, and increases the psychological well-being of patients. Besides, delayed reconstruction is a beneficial option for post-mastectomy radiation therapy (PMRT) cases and reduced the incidence of postoperative complications than immediate reconstruction.
