The practice of using living organisms to treat diseases is known as biotherapy or biologics. This approach harnesses the body’s immune system or utilizes natural substances derived from living sources, such as antibodies, cells, or genes, to promote healing or combat illnesses. Biotherapy can be incredibly effective for various conditions, including cancers and autoimmune disorders. It represents a shift towards targeted therapies that aim to improve patient outcomes with potentially fewer side effects compared to traditional pharmaceuticals.
