Medical research is the process of studying health and disease to improve patient care and treatment. Scientists and doctors work together to discover new medicines, understand illnesses, and find better ways to prevent and manage health issues. This research can involve clinical trials, where new treatments are tested on volunteers, or laboratory studies that explore how diseases affect the body. Through medical research, breakthroughs like vaccines and advanced surgical techniques have been developed, saving countless lives. Organizations such as the National Institutes of Health (NIH) and World Health Organization (WHO) play crucial roles in funding and guiding these studies, ensuring that findings are shared and applied globally.
