Precision medicine is critical to improving cancer outcomes, according to the American Cancer Society Cancer Action Network (ASC CAN). One way they can be improved is by expanding biomarker testing, which is what allowed Sydney Barned, MD, to get the targeted treatment that has extended her life. ASC CAN is working state by state to help pass legislation that expands coverage of and access to biomarker testing. Barned testified before the Maryland legislature about the positive impact the testing had on her life, helping to get a bill passed and signed into law by Governor Wes Moore in 2023. “That’s one of my proudest moments in advocacy,” she says. In total, 14 states have now passed such laws, and in 2023, legislation was introduced in eight more.
