Dr. Samuel Achilefu, a professor of radiology and biomedical engineering at Washington University, things special goggles could help surgeons eradicate cancer cells. Under normal circumstances, these cancerous cells are hard to differentiate from their healthy counterparts. Wearing the high-tech glasses designed by Achilefu and his colleagues, surgeons see cancer cells as glowing blue clusters, helping to reduce the possibility that the patient will have to come back for a second procedure.
