Immunotherapy boosts the body’s own immune system to fight cancer. It’s transforming how many aggressive tumors are treated today.
Unlike chemotherapy, which kills both healthy and cancerous cells, immunotherapy targets cancer cells by activating immune responses.
Common types include checkpoint inhibitors, CAR-T cell therapy, and cancer vaccines.
Patients may experience fatigue, inflammation, or flu-like symptoms, but long-term survival rates are improving.
Immunotherapy is now standard for many advanced cancers like melanoma, lung, and bladder cancer.
Future research focuses on combining immunotherapy with other treatments like radiation or targeted drugs to improve outcomes.
