The majority of cfDNA research is focused on DNA originating from cancer (ctDNA). In short, the DNA from cancer cells gets released by cell-death, secretion or other mechanisms still not known. The fraction of cfDNA released by tumor cells in circulation is influenced by the size of the tumor as well as the tumor stage and type. Early stage cancers and brain tumor are among the most difficult to detect with liquid biopsy.
