File under, “awesome emerging medical technologies”: Johnson & Johnson’s prototype blood test for cancer is being fast tracked to the market.  This ingenious new technology is a blood test so sensitive that it can detect even a single cancer cell from a sample taken from a patient.  Performed simply in a doctor’s office, this blood test promises to be a boon in the early detection of breast, prostate, colon and lung cancer.Dr. Daniel Haber, one of the test’s inventors and chief of Massachusetts General’s cancer center says, “This is like a liquid biopsy” that avoids painful tissue sampling and may give a better way to monitor patients than periodic imaging scans.
