Understanding What People Want to know About Multi-Cancer Blood Tests
Official title: Investigating Information Preferences, Risk Perceptions, and Tradeoffs in Multi-Cancer Early Detection Decisions: A Randomized Vignette Trial
Funded at Dartmouth College · NIH-11429789 · Data updated 2026-11-12
A large study will test how different information about multi-cancer blood tests affects how adults 40-74 decide whether to use them.

Who could benefit from this research
✓Could help
Adults aged 40-74 without a prior cancer history who are representative of the US population.
✕Less likely to help
People who are not considering cancer screening or who have strong preferences for minimal information may not benefit.
What this research studies
This study asks people to consider different fact patterns about a blood test that could detect many cancers and gathers their choices. Participants will read short scenarios and respond to how much detail they want about test accuracy, follow-up tests, and costs. The goal is to make patient-facing information clearer so people can make informed decisions about MCED tests. The research uses a diverse national sample and a randomized design to compare different information formats.
Why it matters
Potential benefit: If successful, results could lead to clearer patient information and better decision-making around MCED cancer screening.
How similar studies have gone: Prior work in health information formats suggests that how information is presented can change decision intent, but this exact MCED-focused approach is innovative.
