Cancer, a relentless and devastating disease, has challenged medical science for centuries. Over the years, various treatments have been developed, from surgery to chemotherapy and radiation therapy. While these approaches have saved countless lives, they often come with debilitating side effects and limited efficacy, especially in advanced cases. However, a new era in cancer treatment has dawned with the advent of immunotherapy. This groundbreaking approach harnesses the body’s own immune system to fight cancer cells, offering hope for more effective and less toxic treatments.
