Medicine, PRE-SUR

Humans have long sought to find cures for the ailments and injuries that befall them. This has led to a long history of diverse attempted treatments, including herbal remedies, leeching, hydrotherapy, acupuncture, homeopathy, and more, all the way up to the most recent science-based treatments that have come into use during the development of today's modern medicine. Medical research and the study of the causes of disease have led to rapid and significant advances in medicine, improving both the efficacy of treatments and our understanding of illnesses and how they operate. The importance of preventive medicine has grown, and the field of medicine has become increasingly specialized as medical disciplines and branches such as endocrinology, immunology, psychiatry, radiology, epidemiology, and nanomedicine have emerged.
