Deep dives
The Origin of Liquid Biopsy
Liquid biopsy represents an innovative approach to cancer detection, fundamentally changing how tumors are diagnosed and monitored. Traditionally, biopsies involved invasive procedures to extract tissue samples, but liquid biopsies use blood samples to analyze cancer DNA, significantly reducing patient discomfort and risk. The method leverages tumor-derived DNA fragments circulating in the blood, allowing for non-invasive detection of localized cancers such as lung and liver cancer. As this technology continues to advance, liquid biopsies are also being used for prenatal diagnostics and monitoring organ transplant rejection, showcasing its potential across various medical fields.
