Much of the "War on Cancer" money goes to curing the disease but in the latest issue of Wired, Thomas Goetz writes about the Canary Foundation, which is focused on early detection. There, researchers are working on developing biomarker blood tests -- using proteomics to pinpoint proteins -- and new imaging tools. "A good biomarker will tell us something we don't know. But even worse is when you think you have a good biomarker, and it's telling us something we don't actually want to know," Martin McIntosh says.
