What the Evidence Shows
Since Donald Trump took office as the 47th President in January 2025, his administration has enacted plans to reduce funding for cancer research substantially. Multiple credible sources report that billions of dollars have been cut or delayed from key federal agencies responsible for cancer research, such as the National Cancer Institute (NCI) and the National Institutes of Health (NIH).
The Guardian (June 2025) highlights a plan by the Trump administration to cut nearly $2.7 billion from the NCI budget, alarming cancer experts about potential increases in patient mortality.
The New York Times and Senator Bernie Sanders' reports confirm that approximately $2.7 billion in NIH research funding was cut through March 2025, affecting cancer and other disease research areas.
Legal challenges have temporarily blocked some of these cuts nationwide, indicating the severity and controversy surrounding the administration's funding decisions.
Additional reports from Forbes and STAT News describe delays in grant disbursements and elimination of funding for specific cancer research programs, further impacting ongoing studies and clinical trials.
Overall, these actions represent a clear reduction in federal support for cancer research starting with the Trump administration's term in 2025, consistent with the claim that cancer research funds were cut after January 2025.
