Analiza din sânge care poate identifica tumorile

Liquid biopsy allows for the analysis of circulating tumor DNA, providing insights into cancer characteristics without tissue samples. This method is particularly useful when tissue is insufficient or difficult to obtain. It enables repeated testing to monitor molecular changes during treatment, although a negative result does not rule out tumor modifications. Genetic testing aims to identify molecular alterations that can guide treatment decisions, potentially leading to targeted therapies. Results are interpreted by oncologists considering various factors related to the cancer.
