Study on the Cosmetic Outcome and Safety Evaluation of 3D Printed Biodegradable Biological Mesh for One-Stage Breast Reconstruction After Radical Mastectomy

This study is evaluating the safety and cosmetic outcomes of using a 3D-printed biodegradable biological mesh during immediate implant-based breast reconstruction following mastectomy for breast cancer. The mesh is designed to support the implant and break down naturally over time. **You may be eligible if...** - You are a woman aged 18 to 70 with confirmed invasive breast cancer - You are unable to have or are choosing to have a full mastectomy rather than breast-conserving surgery - You want immediate breast reconstruction with an implant at the time of mastectomy - You are in good overall physical condition (ECOG 0–1) **You may NOT be eligible if...** - Your breast cancer has already spread to other parts of the body (Stage IV) - You have inflammatory breast cancer or cancer in multiple areas of the breast - You have had another cancer in the past 5 years - You are pregnant - You have had prior radiation to the chest area Talk to your doctor to see if this trial is right for you.
