The difference of digital mammography from classical mammography is the shortage of examination time. Images can be monitored just 1 minute after scanning. The doses of radiation are lower than classical mammography and the image quality is higher. Just because microcalcification (unstable small calcification points) and small lesions can be noticed easily it makes the examination of fibrocystic breast tissue easier too. Detection of such small breast cancer mass, not having detected by hand yet, in early stages is crucial and life-saving. Mammography is advised by experts to people who is older than 40 to do annually.
