Human Mammary Gland Structure (image) Purdue University Caption This image shows a live human mammary gland structure created in research that uses a new imaging technology to reveal subtle changes in breast tissue, representing a potential tool to determine a woman's risk of developing breast cancer and to study ways of preventing the disease. Unlike conventional cell cultures, the 3-D cultures have the round shape of milk-producing glands and behave like real tissue.
