Breast implant surgery complications can arise due to infection, capsular contracture, implant rupture, or asymmetry. Capsular contracture occurs when scar tissue hardens around the implant, while ruptures or leaks may happen due to trauma or implant aging. Prevention includes choosing a qualified surgeon, following post-operative care, and opting for high-quality implants. Techniques like minimally invasive surgery and advanced implant materials in 2025 improve safety and reduce risks, ensuring better long-term results for patients.
