In an eight-year study of more than 600 community-dwelling older adults, researchers say they have further linked levels of cell-free DNA (DNA fragments resulting from cell death) circulating in the ...

Researchers are reporting progress on a blood test that can detect multiple cancers in a relatively simpler, and potentially less pricey, way than other tests under development. The test picks up ...

Researchers have developed a new machine-learning model to detect cancers that are in their early stages of disease by examining DNA fragments from cancer cells in the blood. A University of ...

When a cell dies in a tumor, a growing fetus or elsewhere in the body, bits and pieces of its DNA enter the bloodstream. A new test that identifies the source of such DNA could make it easier to find ...
