U.S. scientists are developing a technology designed to monitor the spread of skin cancer by “listening” to sounds emitted by skin cancer cells using a new minimally invasive procedure, United Press International reports. Developed by researchers at the University of Missouri-Columbia, the technique called photoacoustic detection is able to cause melanoma cells produce a sound that hopefully will allow oncologists to detect early warnings of metastases well before cells spread beyond the skin into other organs. The sounds are high-frequency ultrasounds that researchers can pick up with special microphones for analysis on a computer. The research was first detailed in the Optics Letters journal.
