What is Cancer:
Cancer is a complex and devastating disease characterized by uncontrolled growth and division of abnormal cells. It can occur in any part of the body and has the potential to spread to other tissues and organs, leading to life-threatening complications. The development of cancer is often influenced by genetic mutations or alterations that disrupt the normal regulation of cell growth, division, and death.

Growing Interest in Exosome-Based Cancer Applications
Potential of Exosomes in Biomedical Applications
One area of interest is the use of exosomes as biomarkers for cancer diagnosis and prognosis. Exosomes carry a cargo of biomolecules, including proteins, nucleic acids, and lipids, that reflect the characteristics of their cell of origin. By analyzing the content of exosomes isolated from body fluids, such as blood or urine, researchers can identify specific biomarkers associated with different types of cancer. This non-invasive approach has the potential to revolutionize cancer diagnostics, enabling early detection and personalized treatment strategies.
Exosomes have been investigated for their role in intercellular communication within the tumor microenvironment. They can transfer signaling molecules and genetic material, influencing tumor growth, angiogenesis, immune response, and metastasis. Understanding the complex interplay between exosomes and cancer cells may lead to the development of novel therapeutic approaches targeting key pathways involved in tumor progression and metastasis.
The growing interest in exosome-based cancer applications signifies the increasing recognition of their unique properties and potential in advancing our understanding of cancer biology and improving cancer diagnosis and treatment.

Potential of Exosomes in Biomedical Applications
Tumor Promotion:
Exosomes derived from cancer cells can contribute to tumor growth and metastasis by various mechanisms. They can transfer oncogenic molecules, such as proteins, nucleic acids, and lipids, to recipient cells, promoting cell proliferation, angiogenesis, and invasion. Additionally, cancer cell-derived exosomes can educate surrounding cells and create a pro-tumorigenic microenvironment by suppressing immune responses, inducing inflammation, and remodeling the extracellular matrix.Immune Evasion:
Exosomes released by cancer cells can exert immunosuppressive effects, enabling tumor immune evasion. They can carry immune checkpoint molecules, such as PD-L1, which engage with immune cells and inhibit their anti-tumor activity. Moreover, exosomes can impair the function of immune cells, including cytotoxic T cells and natural killer cells, by delivering immunosuppressive molecules or inducing immune cell apoptosis.Anti-Tumor Effects:
Interestingly, exosomes derived from certain immune cells, such as dendritic cells, can exhibit anti-tumor effects. These exosomes can carry tumor antigens and immune stimulatory molecules, promoting anti-tumor immune responses. They can activate cytotoxic T cells and natural killer cells, enhancing their ability to recognize and eliminate cancer cells. Furthermore, exosomes from mesenchymal stem cells have shown anti-tumor properties by modulating the tumor microenvironment and inhibiting tumor cell proliferation.Diagnostic and Prognostic Markers:
Exosomes hold promise as diagnostic and prognostic markers in cancer. The content of exosomes, including specific proteins, nucleic acids, and microRNAs, can reflect the characteristics of the tumor and provide valuable information about disease progression, response to treatment, and patient outcomes. Analysis of exosomal biomarkers in liquid biopsies, such as blood or urine samples, offers a non-invasive approach for cancer diagnosis and monitoring.Tumor Promotion:
