Biomarker Discovery


Biomarkers are used to measure cancer risk and indicate the presence of a tumor in a tissue. They reflect the molecular mechanisms driving the development of a tumor and could be used to influence treatment decisions. Circulating cell-free DNA (ccfDNA) has received recent attention as a promising biomarker present in blood plasma.

Circulating Cell-Free DNA


ccfDNA is an important biomarker for certain tumors. The quantity and sequences of ccfDNA molecules found in plasma can indicate the presence of a tumor and offer valuable insights into its characteristics.
