Scientists have pioneered a new approach to detecting cancer cells, one that could eventually allow doctors to discover many malignancies earlier than currently possible. The scientists at the University of Florida have successfully tested the technique to find leukemia cells and believe that it opens the door to the first systematic approach to diagnosing cancer at the molecular level. Not only that, but what they describe as a potentially new cancer probe may one day offer a better method of targeting individual cancer cells with drug therapies, reducing side effects from chemotherapy treatments that today affect both healthy and sickly cells.
