What we detect
When tumor activity destroys immune cells and other
healthy tissues, fragments of DNA and RNA continue to
circulate, cell-free, before being reabsorbed. Other cell-free
nucleic acids are shed directly by the tumor itself.
Taken together, cell-free (cf) biomarkers, which also include
circulating proteins, provide a real-time snapshot of cancer’s
activity in the body, with revolutionary implications for screening and treatment.
