Combination therapy is a medical treatment approach that uses two or more different therapies to enhance effectiveness. This method is often employed in treating various conditions, such as cancer, HIV, and autoimmune diseases. By combining medications or therapies, healthcare providers aim to target multiple pathways of a disease, potentially leading to better outcomes and reduced resistance. In cancer treatment, for example, combination therapy may involve using chemotherapy alongside radiation therapy or immunotherapy. This strategy can help to attack cancer cells more effectively and minimize the chances of the disease returning. Overall, combination therapy is a valuable tool in modern medicine for improving patient care.
