Medical Sciences are concerned with establishing the diagnosis, treatment, prognosis and prevention of diseases. 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 such as cholera, malaria, polio, smallpox etc. It has been one of the major factors responsible for the increase in life expectancy. Today, complicated procedures such as heart transplants, brain surgeries, in vitro fertilization, artificial limbs and CRISPR-based gene editing in embryos are made possible by the great strides being made in this field.
