“…A diagnostic tool, which increases patient throughput in skin cancer screening and improves the diagnostic accuracy, would help to detect tumors before they metastasize and also to cut the numbers of unnecessary biopsies. Despite substantial research, diagnosis techniques such as impedance spectroscopy [119], multispectral imaging [120], confocal laser scanning microscopy [121], infrared spectroscopy [122], and Raman spectroscopy [123] have not yet made a breakthrough into clinical use and visual inspection remains the main diagnostic procedure. Millimeter-wave skin cancer diagnosis could fill the gap.…”
