Conversant Bio Blog How cfDNA is Changing Cancer Treatment

IntroductionCell free DNA is revolutionizing the way cancer is detected, diagnosed, and treated.In the many decades of cancer treatment, one of the largest challenges in the treatment of cancer is finding it. Cancer is particularly good among diseases at "hiding". It mimics different biomolecules and signals to keep the immune system in the dark and doesn't give any indication of its existence until it is in its deadly later stages.For years, doctors and researchers have searched for a biomarker, a chemical released by the body that can act as indicators for different conditions, that could be easily found in patients that would give away the presence of early stage tumors. Now those efforts are coming to fruition with the development of liquid biopsies using cell free circulating tumor DNA.
