Bioengineering 3D-printed breast tissue could offer a reconstructive solution after breast cancer surgery. Healshape has raised $6.8 million to develop specific 3D bioprinted breast prostheses for mastectomy patients. 3D mammography, known as tomosynthesis, creates 2D and 3D images of the breast from a series of 2D images and increases the ability to detect breast cancer early. This type of mammography is more accurate, less prone to false alarms and more effective for dense breasts. The MammaPrint test analyzes 70 genes and predicts the risk of breast cancer recurrence in women with an early stage, a tumor smaller than 5 cm and negative or 1-3 positive lymph nodes. Women with genomically low risk had a 5-year distant metastasis-free survival of 95.1% without chemotherapy. Postmenopausal patients at very low risk according to MammaPrint have a 20-year breast cancer-specific survival of 97% with limited endocrine therapy. Breast conserving surgery preserves the skin and shape of the breast and is as safe as a mastectomy.
