This Device Could Detect Dozens of Cancers With a Single Blood Test http://www.wired.com/2014/10/miroculus/ I've had too many friends and family suddenly find they have cancer.

You can't exactly look in your body and see a tumor on your liver. I think the age of cheap body scans and blood work should be here.
