Clinical Application of ctDNA in Early Screening of Breast Cancer
- Conditions
- Breast Cancer
- Interventions
- Diagnostic Test: Low depth whole genome sequencing
- Registration Number
- NCT03973034
- Lead Sponsor
- Peking Union Medical College Hospital
- Brief Summary
The investigators aim to evaluate the possibility of clinical application of ctDNA detection in peripheral blood of normal people, benign breast disease patients and breast cancer patients, so as to act as the new techniques or indicators of early screening of breast cancer.
