What is the significance of liquid biopsies in cancer diagnosis?
Liquid biopsies are a non-invasive method for detecting cancer by analyzing circulating tumor DNA (ctDNA) or other cancer-related biomarkers in the blood. This technique offers several advantages over traditional tissue biopsies, including easier sample collection, the ability to monitor treatment response, and the potential to detect cancer recurrence at an early stage. Liquid biopsies are particularly useful for cancers that are difficult to biopsy or for monitoring metastatic disease.
