'The prospect of developing cancer is a frightening one. Sadly, this fear is leading many to undergo dangerous and harmful cancer screenings that, ironically, can cause the very diseases patients hope to avoid.

Any procedure or action needs to be evaluated not just on its benefits, but also on its costs. If a test saves one life but costs two, it’s not a benefit. It is not the benefit but the ratio of benefit to cost that judges a test. It is the unbalanced exposure to the benefits of cancer screening that have placed the public in an uninformed and, therefore, overly trusting and optimistic position.'
