Multiple and Secondary Primary Cancers

Trial reports how a blood test performed in screening for several cancers

Researchers analyzed performance data from the human NHS-Galleri randomized trial, which included 142,250 adults aged 50–77. The multi-cancer early detection test produced positive results in about 0.8% to 1.0% of participants per screening round, but the study’s primary goal—reducing diagnoses of advanced cancer—was not met.
