Circulating Tumor DNA Tests for Early Stage Cancer Diagnosis
The blood-based test for ctDNA can detect tumor DNA in circulation and thus identify even a microscopic cancer that would not be found by other conventional modalities like endoscopy or radiographic imaging.
Circulating tumor DNA (ctDNA) has become one of the crucial components for cancer detection with the increase of precision medicine practice. ctDNA has great potential as a blood-based biomarker for the detection and treatment of cancer in its early stages.
