Ctdna as a cancer biomarker: a broad overview
WebScientists have discovered that dying tumor cells release small pieces of their DNA into the bloodstream. These pieces are called cell-free circulating tumor DNA (ctDNA). For many years, scientists have been on a quest to identify a non-invasive cancer biomarker - a biological molecule found in the blood that indicates the presence of disease. WebAs a tool for oncologic care, PSA is to prostate cancer what ctDNA may be to all solid tumors. Leaving aside the ctDNA “liquid biopsy” for treatment-associated biomarkers, …
