Medical Techniques Using Nanotech

Medical theory and technique today are a vast improvement over the state of the art a century ago. However, by comparison with what could be, medical practice today can only be described as primitive. Surgery creates huge wounds which require days to heal. Cancer therapy usually aims to be as destructive as possible, without wiping out anything too important. Most of our drugs were discovered by trial and error, and their side effects are sometimes drastic. Organ transplantation requires crippling the immune system. Many conditions cannot be cured at all. The good news is that even basic nanotechnology can correct most if not all of these problems.
