Yet, their distinctive properties also present them as valuable tools for cancer diagnosis. Tumor-derived exosomes, abundant in body fluids, are promising candidates for liquid biopsies, offering non-invasive biomarkers that can aid in cancer detection, prognosis, and real-time monitoring of disease progression. Beyond diagnostics, exosomes are at the forefront of cancer immunotherapy, particularly in developing exosome-based vaccines and targeted therapies.
