Spanish researchers have patented a new method of identifying cells for metastasis in cancer , with a simple blood analysis . A world - first , it could lead to the development of new anti - tumoral drugs and more personalised treatments against cancer . Liquid biopsies can obtain biological information about tumour ##s when a solid biopsy is not possible , such as metastatic breast cancer . In addition , they can detect if the therapeutic targets will remain constant over time , which is vital , given that tumour cells can retain their genetic characteristics throughout the tumoural process . That's why it's mandatory to further study how these tumor cells work and to stablish therapeutic targets against them". Earlier identification and response , which could avoid over - treatment and high toxicity , would also reduce health spending .
