Extreme Density may mean extremely elevated lifetime risk of breast cancer for some women. Other risk factors, environmental and socioeconomic considerations, and the limitations of mammography combine to put lives at risk. Join the Movement to work for better early detection of breast cancer in women with extremely dense breast tissue AND to help women with extremely dense breast tissue use mammography in a more informed way.


  • Over 10% of women receiving mammography have breast so dense their mammogram may fail to see any abnormality over 40% of the time
  • Worse, the same density that makes the mammogram hard to read doubles the woman’s lifetime risk of cancer from around 1 in 8 to 1 in 4.
  • Some mammographic advertising is misleading because current mammogram technology cannot yet overcome its limitation for women with extremely dense breast;
  • No public health entity has fully taken responsibility for breast cancer risk factor education for women with extremely dense breasts;

  1. Truthful, clear, complete, accurate and different mammogram screening and diagnostic effectiveness disclosure for women with extremely dense breast tissue. Disclosures for extremely dense and heterogeneously dense categories should differ.
  2. Improved standard of diagnostic care for women with extremely dense tissue who report a lump or other change in their breast. An offer to biopsy and MRI with contrast in addition to mammogram and ultrasound should be required.  This is a particularly important requirement as the time required by the physician office to work with the insurance company may incentivize the physician business to avoid recommending MRI.
  3. Mandatory risk factor education protocol for women with extremely dense breast tissue at at each mammogram visit. Using clear language and basic diagrams showing increased lifetime risk for extreme breast density and other major risk factors collected at time of mammography.  If the risk data is known due to mammography and / or collected at time of mammography, then the risk data must be used to educate.
