The concept of “healers” has existed for hundreds, if not thousands of years. But ever since the renaissance in western Europe in the 1500s, medical practices really took off. However, diagnostic medical practices were pretty dire, even as late as the 1950s, but with rapid technological innovations, diagnosing diseases and disorders have become much safer, and have led to a massive reduction in deaths during diagnosis. Nowadays, if a doctor wants to examine a peculiarity in the brain, he can use an MRI (Magnetic Resonance Imaging) machine to find out the issue with great accuracy. CT scans have greatly reduced intrusions women have faced when checking with issues pertaining to pregnancy. Overall, there has been great change in such a short span of time, but innovation still continues to this day, with more innovations being introduced.
