ALEXANDRIA, Va. - Two blood tests show promise as screening tools to identify patients with cancer of different types and across different stages. Results from the two approaches will be presented at the ASCO Breakthrough meeting October 11-13, 2019 in Bangkok.
While the technology and science behind the two tests to be presented are complex, the concept is simple. Collect a blood sample. Screen it for cancer. Detect and diagnose cancer at an earlier stage.
While both approaches use cell-free DNA to identify molecular signals of cancer, one of the approaches also uses protein marker results. Cell-free DNA is degraded DNA fragments circulating through the bloodstream, which can come from a number of sources, including tumor cells that have died and released DNA fragments.
