Patient Questions and Answers on DMIST


Is digital mammography better than film?

Overall, there was no difference in detection rates. Only in certain groups was digital shown to be better: women under 50, pre- and perimenopausal women, as well as women with dense breasts. Also, there is no information as of yet, whether survival rates were increased as a result of the higher detection rates and there is no specific information as of yet, as to the types of cancers that digital or standard mammography may be better at detecting.

Who would benefit from digital screening mammograms?

Women who fit in ANY of these 3 categories:

  • Under age 50 (no matter what level of breast tissue density they have)
  • Of any age with heterogeneously (very dense) or extremely dense breasts
  • Pre- or perimenopausal women of any age

Should I switch to a facility that provides digital mammography?

The type of mammography unit is only one factor that influences benefit from the examination. Women should have their mammograms read by a radiologist in whom they, and their physician, have the most confidence.

Should I still have my mammogram performed annually?

Women ages 40 and above should have their mammogram every year. The length of time between mammograms should not be extended in order to change facilities in search of digital technology.

Is the radiation dose lower with digital technology?

In the DMIST trials, digital mammograms required approximately three quarters the radiation dose of film mammography. The dose in film mammography is quite low and poses no significant danger to patients.
