Microwave spectroscopy in skin cancer detection and diagnosis

The use of microwave signals to detect and characterize incidences of skin cancer is an area of research that is relatively unexplored. This paper describes an ongoing effort made toward detection of the differences in the responses of normal skin and benign and cancerous lesions when exposed to nonionizing microwave radiation. Research to date has focused on the characterization of non-biological dielectric samples with known properties and predictable responses. New data include those obtained using an open-ended waveguide antenna, and layer extraction results using signal cancellation
