The American College of Radiology and American Cancer Society recommend yearly mammograms starting at age 40.
There are 39 million mammograms performed in the United States per year.
Approximately 50% of women over 50 get a yearly mammogram in the United States.
Costs of a single mammogram vary, but in general a mammogram cost is about $200-300. Insurers cover mammograms as a preventive service.
It is estimated that mammograms save 1 life for every 1000 tests performed.
Mammography has a false-negative (missed cancer) rate of at least 10 percent. One reason for this is in women who have dense breast tissue which can make it harder to see a tumor.
A new type of mammogram is called three-dimensional mammography, which is also known as digital breast tomosynthesis (DBS). This type of testing has twice the amount of radiation as traditional mammograms, and is believed to make it easier to see tumors in women with dense breast tissue.
