Sound Waves Detect Skin Cancer

November 1, 2006

Hope for early melanoma detection lies in new technique that reads the signature of metastasizing with just 10 cancer cells.


(Optical Society of America) Researchers at the University of Missouri-Columbia have developed a technique to detect the spread of skin cancer cells through the blood by listening to their sound. The minimally invasive technique uses a laser to make the melanoma cells emit ultrasound noise. The technique could enable oncologists to spot the early signs of metastases from as few as ten cancer cells in a blood sample - before they even settle in other organs.
