How Do I Know if I Have Dense Breasts?
Our breast care team has access to the latest state-of-the-art technology, like 3DMammography™ and Volpara™, to better assess your breast density and ensure each image in your mammogram is of the highest quality possible. If a recent mammogram showed you have “dense breasts,” don’t worry. It’s normal and fairly common. In fact, it is estimated that 40–50% of women between 40 and 70 years old have dense breasts.

A description of your breast density is included in your mammography report read by our radiologists. They use a reporting system called BI-RADS to identify the level of density. The levels are:
Breast density is a risk factor for developing breast cancer. It also plays a significant role in radiologists’ ability to detect breast cancer because it can make spotting cancer more difficult.
