Blood test to find cancer early in high-risk families

This trial is testing whether a blood test that detects tiny pieces of cancer DNA can find cancer earlier in people who carry genetic mutations that increase their cancer risk. The researchers want to see if this blood test, when done regularly, can catch cancer at an earlier stage than standard screening methods—and whether doing so saves lives.

People with inherited cancer syndromes need frequent screening to catch cancer early, but current methods can miss cancers or detect them late. This study is testing whether a simple blood test could provide an easier, more frequent way to detect cancer earlier and improve outcomes for these high-risk families.
