Breast implants are the most common way of rebuilding the shape of the breasts after breast cancer surgery. However, current breast implants cannot completely match individual differences in breast shape. It is also often difficult to match the fixed shape of an implant to the opposite healthy breast. As a result, secondary surgeries on the opposite healthy breast are often needed to match size and shape with the implanted breast. The purpose of this study is to collect marker-based computed tomography (CT) and three-dimensional (3D) photo images of the upper body of breast cancer patients. The researchers will use the CT and 3D photo images to create a computer-based model. This computer model will ultimately be used to custom design 3D-printed breast implants for breast cancer patients.
