Testing new blood tests to catch nasopharyngeal cancer early

Researchers are testing whether new blood tests—including ones that look for specific DNA changes and virus markers—can catch nasopharyngeal cancer earlier and more accurately than current standard tests. This study will compare these newer approaches with the tests doctors already use, like checking for Epstein-Barr virus DNA and antibodies in the blood.

Nasopharyngeal cancer can be hard to catch in its earliest stages, when treatment works best. Current blood tests sometimes miss cancer that's present or trigger false alarms in people who don't have it. This trial aims to find better blood tests that are more accurate and catch more early-stage cancers while reducing unnecessary worry and follow-up testing.
