Medicine is a wide term that refers to a variety of health-care methods that have arisen to safeguard and promote healing through illness prevention and treatment. Modern medicine uses biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and p- -revent injury and disease, typically with pharmaceuticals or surgery, but also with talk therapy, external splints and traction, medical devices, biologics, and ionising radiation, among other forms of treatment.
