Tumor immunology is the study of how the immune system interacts with and responds to tumors. This field seeks to understand how tumors evade the immune system, how immune cells can be harnessed to target and destroy tumors, and how the immune response can be manipulated to enhance the effectiveness of cancer treatments. Researchers in tumor immunology are working to develop new immunotherapies that can boost the body's natural defenses against cancer and improve outcomes for cancer patients.
