Immunotherapy functions in the treatment of cancer primarily by enhancing the body’s immune system so that it can effectively recognize and eradicate cancer cells. Unlike traditional treatments such as chemotherapy or radiation, which directly target and kill cancer cells, immunotherapy aims to utilize the body’s own defense mechanisms.

The immune system is composed of various cells and proteins that work together to identify and eliminate harmful substances, including cancerous cells. In immunotherapy, agents such as monoclonal antibodies, checkpoint inhibitors, and vaccines are employed to stimulate or reinforce this immune response. They can either mark cancer cells for destruction by the immune system or enhance the activity of immune cells, allowing them to better target and kill cancer cells.

This approach has gained significant attention in recent years due to its potential to offer long-lasting protection against cancer, as it can help the immune system remember how to combat cancer cells even after treatment has ended. By focusing on mobilizing and augmenting the natural immune response, immunotherapy represents a novel strategy that shifts the paradigm of cancer treatment toward harnessing the body's own capabilities against malignancies.
