Here's some food for thought:

What type of cancers are you talking about? What subtype? What population are we talking about? What subpopulation? What is the difference between an early diagnostic and prevention? Are CTs and MRIs the right tool for the job? Who is most at risk? How often do you screen your target population? How do you make sure they actually come and do the exams? How do you measure success? Are you ready to deal with the outcomes of the diagnosis?

These are just basic questions really. Some people devote their entire life to these hard topics. The radio host sounded like an "expert" with "great ideas" to an equally clueless audience when really he just has no idea.
