A procedure that uses x-rays to take pictures of the inside of the breast. The pictures are usually taken from two different angles, and a computer or x-ray film is used to make 2-D pictures of the breast. 2-dimensional mammography is used to check for breast cancer and other changes in the breast, such as abnormal lumps, cysts, or calcifications (calcium deposits). Also called 2-D mammography.
