Pinpointing Melanoma
June 18, 2019 | Terry Sharrer
Engineers at two universities, in Canada and Scotland, have developed “. . . [an] inexpensive laser probe provides the required measurements [of a skin lesion] without needing complex lenses or cameras, and generates an easily interpreted numerical result similar to that of a thermometer. The researchers directed the laser onto tissue from volunteer patients and observed changes to the light beam. Larger and denser than healthy specimens, the presence of cancer cells results in distinctive scattering of the light waves. This degree of polarization serves as an optical measurement for skin tissue analysis.” MORE
