In the era of personalized medicine, biomarker testing is a tool the oncology workforce can and should leverage to deliver next generation cancer care.
Every patient’s cancer journey is unique, and in this era of personalized medicine, the oncology workforce has the tools to match the specific needs of patients with cancer. One of those tools is biomarker testing and it plays an important role in facilitating personalized cancer care by allowing oncologists to identify specific genetic mutations and alterations that can guide treatment decisions and enhance treatment efficacy. This testing minimizes a trial-and-error approach, reduces adverse treatment effects, enhances access to clinical trials, and improves prognostic information about the
As with many advances in healthcare, access to biomarker testing has not been available to all patients due to a lack of comprehensive coverage. Medicare patients and even patients with private insurance have access to biomarker testing on a case-by-case basis, considering factors such as the specific test, its purpose, the type of cancer, and the clinical context. Patients with Medicaid, state-based insurance plans, or those who are underinsured, have the least access to testing. Recent developments in state legislative efforts have underscored the importance of reshaping coverage for these patients and creating pathways for access.
Over the last few years, the American Cancer Society Cancer Action Network (ACS CAN) has partnered with several organizations and cancer centers across the country to pass state legislation enabling comprehensive biomarker coverage for all patients. So far, 12 states have passed legislation, and an additional 10 states introduced legislation during the 2023 legislative session.

The recent passage of state laws that emphasize biomarker testing in cancer care represents a significant step forward in personalized care for all. However, policy change is only half of the picture—implementation is the next step. The multidisciplinary cancer care team now has more tools at their fingertips than ever to enable more patients to receive targeted therapies and better outcomes. The navigation and implementation of these new laws requires proactive efforts by providers; collaboration across the multidisciplinary team; greater education for patients; increased engagement with insurance providers; streamlined workflows; and solutions for infrastructure barriers.
The Association of Community Cancer Centers (ACCC) is leading the way through initiatives such as Evolving Biomarkers in NSCLC, Emerging Biomarkers: Innovative Therapies for NTRK Gene Fusion Testing, and Eliminating Precision Medicine Disparities, which offers multidisciplinary cancer care teams guidance and support on navigating the evolving biomarker testing landscape. ACCC is also launching a new program, Improving Access to Biomarker Testing in Medicaid Populations, which will examine patient and provider perspectives on disparities in access and raise awareness on the critical value of comprehensive biomarker testing for all populations.
While hurdles exist, the benefits of integrating biomarker testing into patient treatment plans are clear. By staying informed, collaborating across disciplines, and advocating for patients, oncology providers can navigate the complexities of state laws and successfully overcome implementation challenges. Through these efforts, the potential for improved patient outcomes and more effective cancer treatment can become a staple of next generation cancer care.

At the 2026 ASCO Annual Meeting, the Louisiana Oncology Society received the ASCO Jeffrey C Ward Affiliate Advocacy Award for advancing critical advocacy priorities that have translated into meaningful legislative victories. The Iowa Oncology Society and Washington State Medical Oncology Society were also recognized for their advocacy efforts in 2025 at the meeting, receiving second place awards.
