"You're mixing information about different cancers at different stages," O'Donnell said."It becomes a hard analysis to do when you think about how you approve these , and how you recommend their use." "When you think about the false-positive rates for current, accepted single-cancer screening tests, they tend to be around 10%-11%," Beer said."Here, we're looking at 1% or so."
