I was very moved by the woman's letter, called her, and she told me she was just reading about a new blood test now being evaluated at the University of Michigan that might pick up prostate cancer earlier. I promised to follow up.

The reason we do these specials is to underscore the importance of early detection. We know such tests sometimes miss the early evidence. But our aim is not to scare people away from testing. It is to help viewers get the latest information, and this woman is helping us do just that. With her help, we hope others can save the men they love.
