Cancer immunotherapy is a type of treatment that helps the body's immune system recognize and attack cancer cells. Unlike chemotherapy, which directly targets rapidly dividing cells, immunotherapy works by strengthening or modifying the immune response to better identify and destroy cancer. It has become an important treatment option for several types of cancer and continues to be an active area of medical research. The most appropriate treatment depends on the type and stage of cancer, overall health, and specific tumor characteristics.
The immune system naturally helps protect the body from infections and abnormal cells. Some cancer cells, however, can avoid detection by the immune system.

Cancer immunotherapy has transformed the treatment of several types of cancer by helping the immune system recognize and fight cancer cells. While it is not suitable for every cancer or every patient, immunotherapy can provide meaningful benefits for eligible individuals, either alone or in combination with other treatments. Careful evaluation, regular monitoring, and close communication with the healthcare team are essential throughout the treatment journey.
