Mammographic density is associated with an increased risk of breast cancer. It also reduces the reliability of screening mammography. Among the population targeted by the French screening program, about 28% have dense breasts and 3% have very dense breasts. Breast density varies with age, HRT and mammographic technique. Ultrasonography for dense but otherwise clinically and mammographically normal breasts allows detection of cancers not visible on mammograms. The French program protocol allows the evaluation of results from breast US in this context with regards to the number of detected cancers and false positive rate.
乳腺钼靶密度与乳腺癌风险增加相关。它还会降低乳腺钼靶筛查的可靠性。在法国筛查项目的目标人群中，约28%的女性乳房致密，3%的女性乳房非常致密。乳房密度随年龄、激素替代疗法（HRT）和钼靶技术而变化。对于乳房致密但在临床和钼靶检查中无其他异常的情况，超声检查可检测出钼靶片上不可见的癌症。法国项目方案允许在此背景下评估乳腺超声检查在检测到的癌症数量和假阳性率方面的结果。
