It comes from normal cells and, in some people with cancer, from tumor cells as well. Clinicians most often measure cfDNA through a blood sample as part of a \u201cliquid biopsy\u201d approach. It is commonly used in oncology to support tumor profiling and disease monitoring in selected situations."}
