IL SB2442

Requires mammography service providers to notify patients in writing when mammogram results show dense breast tissue, using specific language defined in the bill.

Defines "dense breast tissue" as heterogeneously dense or extremely dense tissue as classified in nationally recognized breast imaging reporting systems, including the American College of Radiology's Breast Imaging Reporting and Data System.

Mandates that patient notification include information that dense breast tissue is found in approximately 50% of women, may make cancer detection more difficult on mammograms, and may increase breast cancer risk.

Permits facilities to update the required notice language to reflect advances in science and technology while continuing to inform patients about dense breast tissue and its effects on mammogram accuracy.

Specifies that this requirement creates no duty of care beyond providing the required notice to patients.
