New Blood Test May Pinpoint Cancer Tumors

Researchers say using DNA signatures may provide a diagnostic tool for cancer that isn’t invasive.

New research shows promise for a blood test that not only identifies cancer but also pinpoints precisely where tumors are growing.

Published in the journal Nature Genetics, the study describes how a specific DNA signature called CpG methylation haplotypes can indicate both the presence and specific location of tumor cells.

Senior study author Kun Zhang of the Jacobs School of Engineering at the University of California-San Diego and colleagues say their findings could offer a noninvasive method for cancer diagnosis.
