Two reasons: For one, dense breasts make it more difficult to see cancer on an X-ray image, which is what a mammogram is. “The dense tissue looks white on a mammogram and cancer also looks white on a mammogram,” said Dr. Wendie Berg of the University of Pittsburgh School of Medicine and chief scientific adviser to DenseBreast-info.org.
When undergoing a mammogram, tissue density is differentiated with bright and dark spots, with the radiolucent dark areas representing fatty tissue and the radioopaque bright spots representing combined fibroglandular tissue. Assessing the new growth of a tumor as a bright spot is the primary method radiologists use to identify early-stage ...
And if you give a woman a mammogram… I’ve been caught in this cycle for over two decades now. My first benign mass was found when I was 20, and it’s been a slow drip of panic, ultrasounds ...
Mammograms also have a rate of missed tumors, or "false negatives". Accurate data regarding the number of false negatives are very difficult to obtain because mastectomies cannot be performed on every woman who has had a mammogram to determine the false negative rate. Estimates of the false negative rate depend on close follow-up of a large ...

It is typically used for two purposes: to aid in the diagnosis of a woman who is experiencing symptoms or has been called back for follow-up views (called diagnostic mammography), and for medical screening of apparently ...

It has a false-negative (missed cancer) rate of between 7 and 12 percent. [13] This is partly due to dense tissues obscuring the cancer and the fact that the appearance of cancer on mammograms has a large overlap with the appearance of normal tissues. Additionally, mammogram should not be done with any increased frequency in people undergoing ...
