Medical Science deals with establishing the diagnosis, treatment, prognosis, and prevention of disease. Contemporary medicine takes a multidisciplinary approach by employing a combination of medical technology, biomedical sciences, and genetics to diagnose and treat disease, either through pharmaceuticals or through surgery. Advances in medical science have been responsible for containing infectious diseases like cholera, malaria, polio, small pox etc. It has been one of the biggest factors responsible for increasing the life expectancy. Today, complicated procedures such as heart transplants, brain surgeries, in vitro fertilization, artificial limbs, and CRISPR-based gene editing in embryos, are all possible due to the huge strides being made in the field.
