Blood test accurately detects over 50 types of cancer, often before symptoms show

Caption

Identification of cancer status for more than 50 cancer types, as well as tissue of origin localisation, from a single blood draw. Cell-free DNA is isolated from blood samples drawn from a patient without cancer (top) or with cancer (bottom), and subjected to a targeted methylation sequencing assay. Sequencing results identifying methylated (red) or unmethylated (blue) CpG regions are fed into a machine-learning classifier that can identify the presence or absence of cancer, as well as identify the tissue of origin.
