Tumor immunology is the study of how the immune system interacts with tumors. It focuses on understanding how the body’s immune cells, such as T cells and natural killer cells, recognize and attack cancer cells. Researchers aim to identify specific markers on tumor cells that can trigger an immune response, which can lead to new treatments. This field also explores how tumors can evade the immune system, allowing them to grow and spread. By understanding these mechanisms, scientists hope to develop therapies, such as immunotherapy, that enhance the immune response against cancer, improving patient outcomes.
