The use of ctDNA offers several advantages over traditional biopsy methods:
1. Non-Invasive: Unlike tissue biopsies, liquid biopsies are non-invasive and can be performed repeatedly with minimal discomfort to the patient. 2. Real-Time Monitoring: ctDNA provides a real-time snapshot of the genetic landscape of the tumor, which is particularly useful for monitoring treatment response and disease progression. 3. Comprehensive Analysis: ctDNA can reflect the genetic heterogeneity of the entire tumor, potentially providing a more comprehensive understanding of the cancer compared to a single tissue biopsy.
