Three-dimensional simulation of aesthetic outcome from breast-conserving surgery compared with viewing photographs or standard care: randomized clinical trial.

Most women with breast cancer are able to have an operation to remove the cancer while preserving the breast ('lumpectomy'). Whilst cancer control is the most important goal, appearance after surgery has been shown to affect long-term quality of life and is considered when planning treatment. Currently, surgeons simply describe the likely changes in appearance and, for more complex procedures, photographs of other women are shown. Patients themselves have indicated they would like more information regarding the likely changes to their breast after treatment. The authors have developed a way to simulate appearance following lumpectomy and radiotherapy using three-dimensional (3D) photographs. The study invited women undergoing lumpectomy to be assigned at random to one of three groups receiving standard care (discussion), a two-dimensional photograph, or the 3D simulation before their operation. The authors have demonstrated that showing a woman her simulation prior to surgery improves confidence going into treatment.
