Liquid biopsy – An advance diagnostic tool for tracking of tumor cells

Abstract

An eminent tool is required for easy detection of disease aggressiveness, identification, and prognosis of treatment. This shows the importance of a non-invasive procedure called liquid biopsy. Liquid biopsy is a liquid biomarker that identify the tumor markers from human body fluids. The small amount of tissue obtained by needle biopsies may not represent the most aggressive subclones and some remote sites cannot be reached out by needles. Here is a review that will describe and compare and contrast sources such as circulating tumor cells, cell-free DNA, exosomes role in the liquid biopsy field.
