What is Liquid Biopsy?
Liquid biopsy is a simple, non-invasive technique used for detecting cancer. Unlike traditional biopsies, which require tissue samples from a patient’s tumor, liquid biopsies use bodily fluids such as blood, urine, or saliva. These fluids carry tiny fragments of DNA shed by tumors, known as circulating tumor DNA (ctDNA).
How Does Liquid Biopsy Work?
The process starts by drawing a small blood sample from the patient. This sample contains ctDNA, which is then isolated and analyzed. The goal is to find genetic mutations or changes that signify cancer. By identifying these changes, doctors can diagnose cancer even before symptoms appear.
Types of Liquid Biopsies
Liquid biopsies can be categorized based on the type of biomarker they detect. Here are some common types:
- Circulating Tumor DNA (ctDNA) Biopsies: These look for fragments of DNA released by cancer cells into the blood.
- Circulating Tumor Cells (CTCs) Biopsies: These tests detect cancer cells that have broken away from the original tumor and entered the bloodstream.
- Exosome Biopsies: Exosomes are tiny vesicles released by cells, including cancer cells. These biopsies target the DNA and RNA within exosomes.
- RNA and Protein Biopsies: These tests analyze RNA sequences or protein markers in the blood that may indicate cancer.
Applications of Liquid Biopsy
Liquid biopsy offers many benefits over traditional methods. It can detect cancer at an early stage, monitor response to treatment, and track disease progression.
It can also identify genetic changes that could help customize treatment plans. With these advantages, liquid biopsy holds great promise in the fight against cancer.
