UCLA develops world’s fastest camera to hunt down cancer in real time

An interesting statistic to put this article into perspective.<p>1. This system scans 200,000 cells per second. 2. There are 30 trillion blood cells in an average human.<p>We'll have stuff like real time blood filtering eventually and when we do that will be something really really impressive.

If someone had all cancer cells in their bloodstream effectively destroyed, could this indefinitely prevent metastis?
