No, you're onto something here. Modern medicine is not all powerful. It does some things very well, and we live much longer because of it, but there is still so much we do not understand. I'm thankful that there are those that put the time and money into this research that furthers our comprehension.

However, there are plenty of conditions you can develop where modern medicine is only able to contain the symptoms, rather than fix the problem causing them. Autoimmune conditions (such as MS) come to mind here.
