The FDA’s rule change requiring providers to inform women about breast density could lead to a flurry of questions

The U.S. Food and Drug Administration finalized a regulation in early March 2023 that updates mammography reporting requirements. The new regulation goes into effect on Sept. 10, 2024, and will require that all women receive information about breast density following a mammogram. It will also require they be told in their mammogram report that dense breast tissue can mask cancer and make cancer more difficult to detect.
