The Future of U.S. Cancer Research Amid Political and Funding Challenges

Cancer research in the United States has long been recognized as one of the most advanced in the world. Its success stems from a diverse and interconnected ecosystem that includes academic institutions, pharmaceutical and biotech companies, federal agencies, and private foundations. As a seasoned cancer biologist with experience across these sectors, I have seen how each component supports the others. However, recent political shifts and funding uncertainties threaten to undermine this delicate balance.

The U.S. has historically led global cancer research, investing over US$7.2 billion annually through the National Cancer Institute (NCI) alone, since the enactment of the National Cancer Act in 1971. This sustained investment has been instrumental in achieving significant declines in cancer mortality, with death rates dropping 34% since 1991. Over the past five years, the FDA has approved more than 100 new cancer drugs, making the U.S. a global leader in bringing breakthrough treatments to market.

Yet, that legacy faces serious risks. Funding delays, political disruptions, and instability within the research community have caused setbacks. Early-career scientists struggle with unstable funding and limited job prospects, leading many to leave academia. Mid-career researchers are distracted by the chase for scarce resources, and interrupted collaborations threaten multi-year projects. These issues could slow down progress, reduce the pipeline of future discoveries, and delay the development of new treatments — ultimately affecting patients waiting for advances.

The foundation of U.S. cancer research is rooted in federal support, especially since the 1971 legislation expanded the NCI and fostered a robust infrastructure for cancer science. Generations of scientists have benefited from this support, leading to improved survival rates and transforming some cancers into manageable or curable conditions. However, political headwinds have repeatedly threatened this progress. During the Trump administration, budget cuts and policy uncertainties jeopardized funding, and similar issues persist in 2025, with NIH grants being cut or canceled, forcing labs to downsize or shut down.

While philanthropic organizations such as the American Cancer Society and Stand Up To Cancer provide critical early-stage support, their funding is limited compared to federal contributions and often disease-specific. Their nimbleness allows faster response to emerging areas like immunotherapy, but their overall scale cannot replace federal funding.

Private industry plays a crucial role in translating research into treatments. Nearly 80% of the billions spent on cancer drugs in the U.S. come from the pharmaceutical and biotech sectors. However, commercial interests tend to focus on high-profit cancers and fast-track drugs, often neglecting rarer or pediatric cancers and basic science. Rising R&D costs, regulatory hurdles, and investor caution have led to the downsizing or closure of promising startups, which may never bring new drugs to patients without support from public or philanthropic sources.

The increasing cancer burden due to an aging population, disparities across racial and economic groups, and environmental factors pose ongoing challenges. The research system is under strain, with competitive grants, diminishing job security for early-career scientists, and delays in clinical trial progress—all threatening the future of cancer breakthroughs.

To sustain and advance U.S. leadership in cancer research, a renewed commitment to balance public funding, private investment, and nonprofit support is crucial. Ensuring predictable long-term federal budgets, fostering collaborations, supporting young scientists, and promoting equity are essential steps. Although significant progress has saved millions of lives, ongoing support and strategic coordination are needed to continue making strides against cancer.
