05. Breast density
Mammography is still the only tool proven to reduce breast cancer deaths with early treatment.
Dense breast tissue is best seen on a mammogram. This dense tissue cannot be felt as accurately in a clinical breast exam or in a breast self-exam.
Having dense breasts isn’t something you can control and is thought to be inherited in part. Breast density can decrease as you go through menopause.
Levels of density are identified and graded using a reporting system called Breast Imaging Reporting and Data System (BI-RADS). The grading is recorded in your mammogram report using alphabetical letters, which is used in Enhanced Breast Screening.
The levels of density are:
A Almost entirely fatty B Scattered areas of fibro glandular density C Heterogeneously dense D Extremely dense
