🩸 Reading the Clues: How Liquid Biopsy Works in Cancer Detection and Patient Monitoring
Description: A technical explanation of liquid biopsy, a revolutionary, non-invasive diagnostic technique that uses simple blood samples to detect and analyze tumor-related materials, transforming cancer care.
Liquid biopsy is a groundbreaking, non-invasive diagnostic tool that analyzes biomarkers released by tumors into the bloodstream, offering a revolutionary way to monitor cancer. Unlike traditional tissue biopsies, which are invasive and only capture a single snapshot in time from a tumor site, a liquid biopsy can provide continuous, real-time molecular insights from a simple blood draw. The primary materials analyzed are circulating tumor DNA (ctDNA), circulating tumor cells (CTCs), and exosomes.
The core mechanism of liquid biopsy centers on the high-sensitivity detection of ctDNA. As tumor cells die, they shed fragments of their DNA, which carry the specific genetic mutations of the cancer, into the circulation. Advanced sequencing technologies, such…
