Digital vs. Analog Mammography: Understanding the Differences

The American Cancer Society recommends that women start receiving mammogram screenings by the time they are 40 years of age. There are two main types of mammograms that are approved and available to the public.

Function

• Both digital and analog mammograms can detect the possible presence of breast cancer cells and abnormal breast tissue. Most patients will not even notice a difference in the procedure, as the exam is almost identical with both types of machines, with the breast pressed between two plates for a period of time.

Considerations

• Analog mammography machines are more widely used, especially in rural areas with limited access to new technology, making this option a good choice for many women. Digital mammography machines, however, have been shown to detect cancer cells earlier and provide a better map of the breast tissue.

Significance

• Digital mammogram machines use less radiation to provide clearer pictures. Images from digital mammograms are generated in as little as ten seconds, while analog mammogram machines can take up to two minutes of exposure to create a sufficient image of the breast tissue.
