Can you tell me how have recent technology advances shifted focus from treating disease to preventing disease?

Technology: We can now see in the body in ways we never did before and we have rapidly improving blood tests and lots of research. The only downside of this is that we MAY be over-tested and find false positives that trigger more testing. A good primary care doc can guide you through the maze. Unfortunately, many docs are not well-trained in nutrition which is a major factor in wellness and prevention.
