What does immunotherapy aim to do?

Immunotherapy primarily aims to treat diseases, particularly cancers, by harnessing and enhancing the natural power of the body's immune system. The goal is to strengthen the immune response against cancer cells or other pathogens. This approach can involve various methods, such as the use of immune checkpoint inhibitors, monoclonal antibodies, or vaccines that stimulate the immune system to recognize and combat abnormal cells more effectively.

The focus is on increasing the immune system's ability to identify and destroy harmful entities, making it a cornerstone of modern treatments for certain illnesses, particularly oncological conditions. This aligns with the overarching goal of immunotherapy to boost the immune system's functionality to fight disease rather than targeting symptoms or other bodily processes, which is why this answer is the most accurate.
