Liquid biopsy shows its utility in the analysis of cancer
One of the big challenges in the treatment of cancer is its heterogeneity. Tumours can present different mutations and change with time, which means that not all treatments are effective or they generate resistance. That’s why it is important to carry out follow-ups that allow us to identify changes as they are produced. However, getting the precise samples to carry out this analysis via a tissue biopsy isn’t always easy. That’s why, in the last few years, a new method has been developed which allows to analyse tumoural DNA circulating in the blood in order to carry out this follow-up and analysis of cancer in an easy and simple way. This is known as liquid biopsy.
