Research2 shows that a woman with extremely dense breast tissue has approximately five times greater risk of breast cancer than a woman with breast tissue density of <10%, all other factors being equal.
Increased mammographic density makes it more difficult to perceive a breast cancer on a mammogram
Both breast cancers and benign breast lesions (such as cysts and fibroadenomas), appear as white masses on a mammogram. They are therefore difficult to detect if the background breast tissue is also white (ie. fibroglandular) rather than fatty.
3D mammography (Digital Tomosynthesis) has approximately 25% better overall cancer detection rate than 2D (standard) mammography3
At Sydney Breast Clinic, we aim to optimise cancer detection by using the latest digital mammogram technology. Digital breast tomosynthesis, often called 3D mammography, is used for all women having a mammogram. DBT uses a series of angled images reconstructed into slices. This improves cancer detection (sensitivity) and confirms normal findings when superimposed normal breast tissue mimics an abnormality (specificity).
