Abstract : Screening mammography trials have shown that mammography has a sensitivity to breast cancer ranging from 60% to 90%, with a trend toward lower sensitivity in premenopausal women 1,2. In an analysis of missed breast cancers, Bird, et. al. determined that missed breast cancers are more likely to occur in radiographically dense breasts E3. It is known that radiographically dense breasts have a greater probability of masking breast cancers, when they are present, due to the similar x-ray attenuation properties of glandular tissues and breast cancers. The higher the proportion of glandular tissues in the breast, the greater the probability that a breast cancer will be superimposed by normal glandular tissues and, therefore, missed in the mammogram.
