A mammogram that is a digital image is just as effective at finding breast cancer as one done traditionally with X-rays, which is called analog mammography.
Digital technology offers several potential advantages over the current film/screen method for mammography. Unlike film images, digital images:
Can be stored and transferred electronically
Can be manipulated to correct for underexposure or overexposure, potentially eliminating the need for another mammogram
Have a large dynamic range that allows examination of all areas of the breast, despite varying densities
