"As of September 10, 2024, all mammography facilities in the United States must inform a patient after their mammogram if their breasts are “dense” or “not dense”.¹ For those with dense breasts, patients must also receive the following information: “Dense tissue makes it both harder to find breast cancer on a mammogram and raises the risk of developing breast cancer. Your breast tissue is dense. In some people with dense tissue, other imaging tests in addition to a mammogram may help find cancers. Talk to your healthcare provider about breast density, risks for breast cancer, and your individual situation.”¹ The FDA anticipates these notifications will contribute to reduced breast cancer mortality and lower treatment costs.^1"
