Tumor tissue is typically removed and stored as formalin-fixed, paraffin-embedded (FFPE) tissue, a process that preserves the morphological structures well but chemically modifies and degrades the nucleic acids. Liquid biopsies represent an alternative to this, as the cell-free DNA (cfDNA) present in the blood includes DNA derived from cancer cells, facilitating the detection of cancer biomarkers.
