Combination therapy is a medical approach that involves using multiple treatments or medications to target a specific health condition. This approach is often used in the treatment of complex or chronic diseases, such as cancer, HIV/AIDS, and autoimmune disorders. By using multiple therapies that target different aspects of the disease, combination therapy can enhance treatment effectiveness, reduce side effects, and prevent drug resistance. In the context of cancer treatment, for example, combination therapy may involve using chemotherapy, radiation therapy, and immunotherapy simultaneously to target cancer cells through multiple mechanisms. Overall, combination therapy aims to optimize treatment outcomes by leveraging the unique benefits of different therapies in a coordinated and complementary manner.
