Cancer vaccines and immunotherapy represent groundbreaking approaches in the realm of cancer treatment. Cancer vaccines stimulate the immune system to recognize and attack cancer cells, potentially preventing cancer development or recurrence. On the other hand, immunotherapy utilizes substances to enhance the body's immune response, aiding in targeting and destroying cancer cells more effectively. These innovative treatments offer promising avenues by leveraging the body's own defenses to combat cancer, often with fewer side effects than traditional therapies. They signify a paradigm shift in cancer care, showcasing a personalized and targeted approach to treatment, holding great potential in revolutionizing the landscape of cancer therapies for improved patient outcomes and survival rates.
