Summary:An accurate non-invasive electromagnetic skin imaging system requires a precise dermal tissue characterization. Studies related to microwave and millimeter-wave imaging techniques indicate a significant difference in the dielectric properties between healthy and malignant tissues. Malignant tissues tend to have higher water content compared to healthy tissues. Therefore, the dielectric properties of cancerous tissues can be expressed as a function of healthy tissue characteristics and their respective water content. In this work, a formula is derived to calculate the dielectric properties of human skin melanoma (MM) and basal cell carcinoma (BCC) tissues from the properties of healthy skin tissues. The derived formula indicates a significant (20%) difference at 10 GHz between MM and healthy tissues, whereas the difference is 11% for BCC. This substantial difference indicates the possibility of using electromagnetic technique's for non-invasive skin cancer detection.
